    		    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";
 }
}
