    		    This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.optimization.MethodArgumentCouldBeFinal
    		    
		    
	    
	    
        
        
        Example:
            
                    
  
public void foo (String param) {
  // do stuff with param never assigning it
  // better: public void foo (final String param) {
}
