InefficientStringBuffering

Avoid concatenating non literals in a StringBuffer constructor or append().

This rule is defined by the following Java class: net.sourceforge.pmd.rules.strings.InefficientStringBuffering

Example:

                

public class Foo {
 void bar() {
  // Avoid this
  StringBuffer sb=new StringBuffer("tmp = "+System.getProperty("java.io.tmpdir"));
  // use instead something like this
  StringBuffer sb = new StringBuffer("tmp = ");
  sb.append(System.getProperty("java.io.tmpdir"));
 }
}
