PMD

PMD is a free and open-source tool that acts like a buddy for Java developers. It’s designed to analyze source code, helping you catch issues before they become big problems.

What Makes PMD Special?

With PMD, you get a powerful static code analyzer that supports various programming languages. This includes Java, JSP, JavaScript, Salesforce.com Apex and Visualforce, PLSQL, Apache Velocity, XML, and Maven POM. So no matter what language you’re working in, PMD has got your back!

Find Code Issues Fast

This tool helps you quickly spot unused variables and unnecessary object creations. Plus, it flags empty catch blocks and more! Imagine how much time you’ll save by not having to sift through your code manually!

Built-in Rules for Easy Analysis

The best part? PMD comes packed with lots of ready-to-use rules that make code analysis easier than ever. You can also create your own custom rules using XPath if you want to dive deeper into the source code's Abstract Syntax Tree (AST).

A Closer Look at Common Issues

PMD was specifically built to scan Java source code and identify potential problems. Here are some examples of what it looks for:

• Possible Bugs: Empty try/catch/finally/switch statements could lead to unexpected errors.


• Dead Code: It finds unused local variables or parameters that are just sitting there.


• Suboptimal Code: No one wants wasteful String or StringBuffer usage!


• Overcomplicated Expressions: It catches unnecessary if statements or loops that could be simplified.


• Duplicate Code: Copy-pasting code often leads to copy-pasting bugs!
