Java Clean Code Tutorial #2 - Static Analysis FindBugs Eclipse Plugin Setup
 
05:09
Episode 2 of the free Java Clean Code Training Series. In this tutorial I show you how to download and install the static analysis tool FindBugs and run it against your Java Programs in Eclipse or Spring Tool Suite. Findbugs looks for and identifies bugs in Java Programs. It is based on the concept of bug patterns. A bug pattern is a code idiom that is often an error. Findbugs will search for over 200 bug patterns in your code. Bug patterns arise for a variety of reasons: - Difficult language features - Misunderstood API methods - Misunderstood invariants when code is modified during maintenance - Garden variety mistakes: typos, use of the wrong boolean operator, dead code etc FindBugs uses static analysis to inspect Java bytecode for occurrences of bug patterns. Static analysis means that FindBugs can find bugs by simply inspecting a program's code: executing the program is not necessary. This makes FindBugs very easy to use: in general, you should be able to use it to look for bugs in your code within a few minutes of downloading it. Running findbugs will certainly help you write cleaner code by helping to identify bugs, typos, dead code or simple generic coding mistakes. I treat static analysis tools as first class citizens and always execute on my code, regardless if its fun home code or serious production code. Why clean code? Simple. Clean code allows us to confidently make changes and deliver more features quickly to our customers. Don’t forget to subscribe for your regular dose of Java Tutorials! STOP THE ROT.

Nullness Analysis for Java
 
53:30
Google Tech Talks September 17, 2008 ABSTRACT Attempts to dereference null result in an exception or a segmentation fault. Hence it is important to know those program points where this might occur and prove the others (or the entire program) safe. Nullness analysis of computer programs checks or infers non-null annotations for variables and object fields. Most nullness analyses currently use run-time checks or are simply syntactical (as in Eclipse and Idea) or incorrect or only verify manual annotations. We use abstract interpretation to build and prove correct a static nullness analysis for Java bytecode which infers non-null annotations. It is based on Boolean formulas, implemented with binary decision diagrams. Our experiments show it faster and more precise than the correct nullness analysis by Hubert, Jensen and Pichardie. We deal with static fields and exceptions, which is not the case of most other analyses. The result is theoretically clean and the implementation strong and scalable. Speaker: Prof. Fausto Spoto Fausto Spoto is associate professor at the University of Verona, Italy. He took a PhD in computer science from the University of Pisa, where he started working at the static analysis of computer programs. His current interests are related to the analysis of Java and Java bytecode programs. He wrote a tool, Julia, which analyzes Java bytecode programs by using abstract interpretation and presents the results to the user, for verification as well as for code optimisation.

Build a Text Summarizer in Java
 
11:21
Get the Code here : https://github.com/ajhalthor/text-summarizer Follow me on Twitter : https://twitter.com/ajhalthor Take a look at the original by Shlomi Babluki : http://thetokenizer.com/2013/04/28/build-your-own-summary-tool/ TRANSCRIPT OVERVIEW ALGORITHM 1. Take the full CONTENT and split it into PARAGRAPHS. 2. Split each PARAGRAPH into SENTENCES. 3. Compare every sentence with every other. This is done by Counting the number of common words and then Normalize this by dividing by average number of words per sentence. 4. These intermediate scores/values are stored in an INTERSECTION matrix 5. Create the key-value dictionary - Key : Sentence - Value : Sum of intersection values with this sentence 6. From every paragraph, extract the sentences with the highest score. 7. Sort the selected sentences in order of appearance in the original text to preserve content and meaning. And like that, you have generated a summary of the original text. CLASSES IN JAVA PROJECT 1. Sentence : The entire text is divided into a number of paragraphs and each paragraph is divided into a number of sentences. 2. Paragraph : Every paragraph has a number associated with it and an Array List of sentences. 3. Sentence Comparitor : Compare Sentence objects based on Score 4. SentenceComparatorForSummary : Compare Sentence objects based on position in text. 5. SummayTool : akes care of all the operations from extracting sentences to generating the summary. HOW IS MY SUMMARIZER BETTER THAN THE ORIGINAL ? My text summarizer selects number of sentences from a paragraph depending on the length. This is an improvement over the original text summarizer implementation that only selects 1 sentence per paragraph regardless of length. So, If the author decides to crunch everything into 1 paragraph, then only one sentence would be chosen. In the current implementation, we set it to accept several sentences for larger paragraphs. It delivers cogent summaries for general essays, reviews and publications. RUN THIS PROGRAM $ javac -d bin improved_summary.java $ java -classpath bin improved_summary

Combining R with Java for Data Analysis
 
51:05
Java is a general-purpose language and is not particularly well suited for performing statistical analysis. Special languages and software environments have been created by and for statisticians to use. Statisticians think about programming and data analysis much different from Java programmers. These languages and tools make it easy to perform very sophisticated analyses on large data sets easily. Tools, such as R and SAS, contain a large toolbox of statistical tools that are well tested, documented and validated. For data analysis you want to use these tools. In this session we will provide an overview of how to leverage the power of R from Java. R is the leading open source statistical package/language/environment. The first part of the presentation will provide an overview of R focusing on the differences between R and Java at the language level. We’ll also look at some of the basic and more advanced tests to illustrate the power of R. The second half of the presentation will cover how to integrate R and Java using rJava. We’ll look at leverage R from the new Java EE Batching (JSR 352) to provide robust statistical analysis for enterprise applications. Authors: Ryan Cuprak undefined Elsa Cuprak Elsa was a statistician for the Cardiology/Heart Failure and Transplant Departments at Yale School of Medicine. She is an expert in statistics as well as SAS and Excel. Elsa has a masters degree in Actuary Science from the University of Iowa and bachelors in statistics from the University of California Berkley.

ECE2012 - Develop Custom Java Code Analysis and Refactoring Tools with JaMoPP
 
27:32
Jendrik Johannes - DevBoost GmbH Today, Java code makes up a large part of many software systems. To keep these systems maintainable, extendable and flexible in the long run, constant checking of the consistency of code and other artefacts is necessary. Individual coding guidelines need to be followed, anti-patterns need to be avoided and interfaces need to be used correctly. To save costs and to prevent mistakes during theses tasks, a high degree of automation is desirable. JaMoPP - the Java Model Parser and Printer - addresses these challenges. JaMoPP automatically converts your Java code into an EMF-conformant model. This model can be processed by any EMF-based tool. Additionally, the model can be linked to other files and models for which EMF support exists. For example, BPMN or UML models, property or CSV files or data from databases. With JaMoPP, custom tools for Java code analysis and refactoring can be defined. This way, inconsistencies in the code or between code and other artifacts can be recognised instantly and, if required, repaired automatically. JaMoPP is integrated with Eclipse to provide instant feedback to developers but can also be utilised outside of Eclipse to run checks and refactorings in build scripts or on continuous integration systems. In this talk, we demonstrate the capabilities of JaMoPP and its integration with Eclipse and EMF on multiple practical examples.

Visual Java Source Code Dependency  Cycle Analysis with Chord Diagrams
 
09:50
Live Demo http://www.iunera.de/codedependencywithchord/index.html Github: https://github.com/iunera/codeanalysis This project is a proof of concept to demonstrate the advantages of a visual chord-diagram based investigation of software dependencies. The goal is to show that this graphical representation enables to detect and to analyze a program without having to know the implementation details on a detailed source code level. The application of the project can be used for business cases like quality gates or to plan refactorings to decouple or rearrange packages. The data origin for the demo diagram were created by computing coupling indicators of the Eclipse Communities Java development tools (JDT) with the Hypermodelling technology. Please give Feedback in the comments. Live Demo http://www.iunera.de/codedependencywithchord/index.html Source Code and explanations https://github.com/iunera/codeanalysis Background In general, a software architecture goal to create reliable and reusable software artifacts is to develop loosely coupled software components. Furthermore, strong source code dependencies inflict source reuse and engineering problems. However, even that it is well-known that restricting dependencies is a good thing, software engineers often cannot avoid them when manufacturing systems in the first place. Commonly, a software system is developed by iterative steps and the dependencies grow in the continuous development process. This results in the process that the dependencies have to be maintained over time and refactoring steps have to be taken to manage and reduce dependencies over time. Once the development of code foundation of a software system grows, the management of dependencies gets more and more complex. In order to reduce dependencies, developers need to know which artifacts consume other artifacts. Today, mostly this work is done by inspecting the source code manually. Usually the developers tediously gather the artifacts that belong to the desired dependencies and then try to reduce them. Additionally, software and their dependencies are multi-dimensional construct and manifold what makes the inspection even more difficult. When we saw complex chord diagrams about the financial crisis (check it here) we got motivated us to use chord diagrams to investigate software dependencies in a visual manner. Hence, we develop a complete Javascript solution to leverage the power of chord diagrams to analyze the dependencies of programs in a top down approach. This way, investigations of the dependencies of program components can be done in a visual and intuitively understandable way. This solution supports the following key features: Permanent marking The user can select software components and the highlighting (just click the border) is done in a permanent way and not faded away once the hover pointer gets moved away. A special feature of the permanent highlighting is that the connected components that are not activated permanently but that are connected to a highlighted component get faded partially. This way, the user can distinguish selected and connected elements, because the selected ones get shown not faded at all and the just connected ones get shown partially. Dependency intensity visualisation The dependency intensity gets visualized in a graphical manner by showing different thick connections Faded association highlighting Selected system components lead to a highlighting of the associated dependencies and the components they lead to Hover tooltips Tooltips get shown once a dependency gets selected, showing details about the intensity Drill-Downs Drill downs enable to get insights of selected component data and their inner dependencies at multiple levels Url parameter diagram state The state of the visualization is stored in URL parameters to enable forwarding an investigation result to other people via a hyperlinks.

KotlinConf 2018 - Safe(r) Kotlin Code - Static Analysis Tools for Kotlin by Marvin Ramin
 
42:01
Recording brought to you by American Express https://americanexpress.io/kotlin-jobs When introducing Kotlin to a Java codebase one thing that is often missing from the picture are static analysis tools. Static Analysis suites can give an overview of a codebases health, point out potential issues to make the code safer and can help to keep the codebase in a uniform style. The Java ecosystem already has a broad selection of different static analysis tools each with a different focus. To cater for the different language features and concepts that Kotlin offers most Java focussed static analysis tools are not applicable to Kotlin code. This talk showcases static analysis tools written specifically to improve Kotlin code (and are mostly written in Kotlin themselves). Tools such as detekt, ktlint and Android Lint are introduced and explored for their use-cases and how they can complement each other. As Marvin is one of the maintainers of detekt he will also share in more detail how detekt works, what it aims to achieve and how the future roadmap looks like for detekt. About the Presenter: Marvin Ramin is a Software Engineer at Google where he is working on Android TV. Previously he was working on multiple Android applications focusing on making their codebases safer and easier to work with. Marvin is also contributing and collaborating on detekt, a Kotlin static analysis suite.

Jie Liu - Mirror: Static and Dynamic Analysis of Java Reflection
 
36:07
Reflection, which is widely used in practice, poses a significant obstacle to program analysis. Reflective calls can be analyzed statically or dynamically. Static analysis can be more sound, but may introduce many false reflective targets and thus sometimes make it unscalable. In contrast, dynamic analysis can be precise, but may miss many true reflective targets due to low code coverage. Jie introduces Mirror, the first automatic reflection analysis for Java that reaps the benefits of both worlds. In it's static analysis, a novel reflection-oriented slicing technique is applied to identify a small number of small path-based slices for a reflective call so that different reflective targets are likely exercised along these different paths. This preserves the soundness of pure static reflection analysis as much as possible, improves its scalability, and reduces substantially its false positive rate. In its dynamic analysis, these slices are executed with automatically generated test cases to report the reflective targets accessed. This significantly improves the code coverage of pure dynamic analysis. Jie discusses how the team evaluated Mirror against a state-of-the-art dynamic reflection analysis tool, Tamiflex, by using a set of 10 large real-world Java applications. Mirror detects 12.5% - 933.3% more reflective targets efficiently (in 362.8 seconds on average) without producing any false positives. These new targets enable 5 - 174949 call-graph edges to be reachable in the application code. With Mirror, more reflective targets can be resolved precisely and quickly, rendering a larger part of the codebase to be visible to many analysis tools such as bug detectors and security analyzers. Bio: Jie liu is a PhD student supervised by Prof. Jingling Xue at School of Computer Science and Engineering, University of New South Wales (UNSW). Jie received his B.Eng degree in Software Engineering from Northwestern Polytechnical University (NPU) in 2014. Before joining UNSW, Jie studied in Fudan University as a postgraduate student from 2014 to 2015. Jie started pursuing his PhD in February 2016. Jie's research interests are program analysis, software engineering and programming languages.

Cette présentation vous promet, en toute simplicité, d’ecrire votre propre analyseur pour Java basé sur SonarQube. Pour y arriver il faudra comprendre les challenges d’analyse du langage, du parsing à l’execution symbolique, pour pouvoir coder des vérifications specifiques à vos projets ! Improve your tests quality with Mutation Testing by Nicolas Fränkel and Evgeny Mandrikov (english talk) Unit testing ensures your production code is relevant. But what does ensure your testing code is relevant? Come discover mutation testing and make sure your never forget another assert again. In the realm of testing, the code coverage metrics is the most often talked about. However, it doesn’t mean that the test has been useful or even that an assert has been coded. Mutation testing is a strategy to make sure that the test code is relevant. In this talk, we will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, we will describe how Mutation Testing work and how it helps pointing out code that is tested but leave out corner cases. We will also demo PIT, a Java production-grade framework that enables Mutation Testing on a simple code base. If time allows, a demo will also show how PIT can be integrated with SonarQube. As usual, this session will end up with a buffet provided by our sponsors Hortis | OOSphere | Qim Info | Serial ilem | Kalyss | Sopra Steria

OW2con'18 Spoon: open source library to analyze, rewrite, transform, transpile Java source code
 
19:17
Spoon is an open-source library to analyze, rewrite, transform, transpile Java source code. It parses source files to build a well-designed AST with powerful analysis and transformation API. It fully supports Java 8 and supports Java 9 modules. Spoon provides a complete and fine-grained Java metamodel where any program element (classes, methods, fields, statements, expressions...) can be accessed both for reading and modification. Spoon takes as input source code and produces transformed source code ready to be compiled. Spoon can be integrated in Maven and Gradle. (Simon Urli, INRIA)

4.16. Budget Analysis - Java
 
47:05
Starting out with Java: From control structures through objects Chapter 4 Programming Challenges 16. Budget Analysis Write a program that asks the user to enter the amount that he or she has budgeted for a month. A loop should then prompt the user to enter each of his or her expenses for the month, and keep a running total. When the loop finishes, the program should display the amount that the user is over or under budget. Gaddis, Tony (2015-05-29). Starting Out with Java: From Control Structures through Objects (Page 265). Pearson Education. Kindle Edition. Thanks :)
