PMD and CPD For Eclipse

PMD

From http://pmd.sourceforge.net/

PMD scans Java source code and looks for potential problems like:

• Possible bugs - empty try/catch/finally/switch statements
• Dead code - unused local variables, parameters and private methods
• Suboptimal code - wasteful String/StringBuffer usage
• Oercomplicated expressions - unnecessary if statements, for loops that could be while loops
• Duplicate code - copied/pasted code means copied/pasted bugs

CPD

From http://pmd.sourceforge.net/cpd.html

Duplicate code can be hard to find, especially in a large project. But PMD's Copy/Paste Detector (CPD) can find it for you! CPD has been through three major incarnations:

• First we wrote it using a variant of Michael Wise's Greedy String Tiling algorithm (our variant is described here)
• Then it was completely rewritten by Brian Ewins using the Burrows-Wheeler transform
• Finally, it was rewritten by Steve Hawkins to use the Karp-Rabin string matching algorithm

Source xmlSource = new StreamSource(xmlFile);

Result ouput = new StreamResult(new FileOutputStream(outFile));

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(xsltSource);
transformer.transform(xmlSource, ouput);

System.out.println("Html got generated");

} catch (Exception e) {
e.printStackTrace();
}
}
