PMD is a static Java source code analyzer. It uses rule-sets to define when a piece of source is erroneous. PMD includes a set of built-in rules and supports the ability to write custom rules. Typically, issues reported by PMD are not true errors, but rather inefficient code, i.e. the application could still function properly even if they were not corrected. ==Features== PMD is able to detect flaws or possible flaws in source code, like: * ''Possible bugs''—Empty try/catch/finally/switch blocks. * ''Dead code''—Unused local variables, parameters and private methods. * Empty if/while statements. * ''Overcomplicated expressions''—Unnecessary if statements, for loops that could be while loops. * ''Suboptimal code''—Wasteful String/StringBuffer usage. * Classes with high Cyclomatic Complexity measurements. * ''Duplicate code''—Copied/pasted code can mean copied/pasted bugs, and decreases maintainability. While PMD does not officially stand for anything, it has several unofficial names, the most appropriate probably being ''Programming Mistake Detector''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PMD (software)」の詳細全文を読む スポンサード リンク
