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. See you in episode 3, Philip http://findbugs.sourceforge.net/factSheet.html

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.

From Java Code to Java Heap: Understanding the Memory Usage of Your Application
 
56:47
When you write and run Java code, the JVM makes several allocations on your behalf, but do you have an understanding of how much that is? This session provides insight into the memory usage of Java code, covering the memory overhead of putting "int" into an integer object and the cost of object delegation and the memory efficiency of the different collection types. It also gives you an understanding of the off-Java (native) heap memory usage of some types of Java objects, such as threads and sockets. Most importantly, the session covers how to determine where there are inefficiencies in your application and how to choose the right collections to improve your Java code.

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

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. She worked for several years as an actuary at both Met Life and the West Coast Life Insurance Company.

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.

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.

Java Heap Dump Analysis - VisualVM Tutorial
 
04:43
In this tutorial I show you how to use VisualVM to perform a Java Heap Dump snapshot in a live executing Java application in eclipse IDE. Ahem… Let me ask…First….What is Java VisualVM? Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications. This includes objects allocated on the Heap, Thread state, Execution environment information, Stack etc. Great for debugging dog slow applications!! Ok cool, now what is a Heap Dump? A heap dump is a snapshot of the memory of a Java Process at a single point in time. This contains data about Java objects, classes in the heap, class, fields, references, class loader names, static content, Thread Stacks etc. And... Why would I create a Heap Dump? There are many, but here are my two favourites. When performing performance analysis on an application, performing a heap dump during certain execution phases will provide you will critical information on the state of the Java Process, such as object allocation on the heap and thread states. Second, when an application crashes due to a Java java.lang.OutOfMemoryError, you can enforce the JVM to perform a snapshot and capture the application’s state via a heap dump. This heap dump will typically be placed into a java_pid*[id].hprof file. You can then load the heap dump file into a visualizer to understand the java applications state – this provides a good insight and clue into why the program crashed. Although if your application is running on a cloud based ephemeral file system this may be tricky. But the majority of applications that require a heap dump for analysis are most likely not in the cloud and rather dedicated high performance data centers.
