LocalVariableCouldBeFinal

A local variable assigned only once can be declared final.

This rule is defined by the following Java class: net.sourceforge.pmd.rules.optimization.LocalVariableCouldBeFinal

Example:

                
  
public class Bar {
 public void foo () {
  String a = "a"; //if a will not be assigned again it is better to do this:
  final String b = "b";
 }
}
