PVS-Studio static analyzer team, which until recently was searching for bugs and potential vulnerabilities only in C, C++, and C# code, has prepared a new version of their tool for Java code as well. Despite the fact that in the Java world there is already a number of static analysis tools, developers believe that their analyzer can be powerful and will be a good competition.

One of developers wrote in his article about the way how PVS-Studio for Java was created. First of all, it was necessary to figure out the development process of a syntax tree and semantic model. As these elements are basic, static analyzer is built around them. In addition to them, the analyzer also requires data flow analysis, which enables you to calculate the possible values of variables and expressions in each point of the program and, thanks to that, find errors. Also the analyzer needs the annotation mechanism, diagnostic rules, integration, testing, and other techniques, explained in detail in the article.

Traditionally, the author gave examples of errors from different open source projects, that the Java analyzer has detected. The author also noted that in the future articles with a more detailed report on each project will be available. So far you can review errors from the Hibernate, Hive, JavaParser, Jenkins projects and several others.

Besides that, when the first alpha version of the Java analyzer is available, developers suggest participating in its testing for those who would like to. To do this, write to their support and they will contact you.

IT conferences and meetings on programming languages see a growing number of speakers talking about static code analysis. Although this field is quite specific, there is still a number of interesting discussions to be found here to help programmers understand the methods, ways of use, and specifics of static code analysis. In this article, we have collected a number of videos on static analysis whose easy style of presentation makes them useful and interesting to a wide audience of both skilled and novice programmers.

What is Static Analysis?

Some of our users run static analysis only occasionally. They find new errors in their code and, feeling glad about this, willingly renew PVS-Studio licenses. I should feel glad too, shouldn't I? But I feel sad - because you get only 10-20% of the tool's efficiency when using it in such a way, while you could obtain at least 80-90% if you used it otherwise. In this post I will tell you about the most common mistake among users of static code analysis tools.

TDD is one of the most popular software development techniques. I like this technology in general, and we employ it to some extent. The main thing is not to run to extremes when using it. One shouldn't fully rely on it alone forgetting other methods of software quality enhancement. In this article, I will show you how the static code analysis methodology can be used by programmers using TDD to additionally secure themselves against errors.
TDD is wonderful
Test-driven development (TDD) is a technique of software development based on iteration of very short development cycles. You write a test first which covers the change you want to introduce, then you write a code to pass the test, and finally you carry out refactoring of the new code to meet the corresponding standards. I won't dwell on what TDD is: there exist many articles on this subject which you can easily find on the Internet.

Static code analysis is the process of detecting errors and defects in software's source code.

Static analysis can be viewed as an automated code review process. Let's speak on the code review now.

Code review is one of the oldest and safest methods of defect detection. It deals with joint attentive reading of the source code and giving recommendations on how to improve it. This process reveals errors or code fragments that can become errors in future. It is also considered that the code's author should not give explanations on how a certain program part works. The program's execution algorithm should be clear directly from the program text and comments. If it is not so, the code needs improving.

More than a year has passed since we analyzed Notepad++ with PVS-Studio. We wanted to see how much better the PVS-Studio analyzer has become since then and which of the previous errors have been fixed in Notepad++.
