Code analyzer: FindBugs and PMD
0 likes437 views
The document discusses two code analysis tools, FindBugs and PMD. It provides an overview of what each tool is used for, how to install them in Eclipse, and mentions configuration options. FindBugs looks for bug patterns in Java code, while PMD scans for potential problems like empty code blocks, dead code, overcomplicated expressions, and duplicate code. Instructions are given on installing each plugin for Eclipse, but details of how to use the tools and configure rules are not provided.
