UselessStringValueOf


UselessStringValueOf
No need to call String.valueOf to append to a string; just use the valueOf() argument directly.
      
		
		
		    
		    
    		    
    		    
    		    

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

public String convert(int i) {
  String s;
  s = "a" + String.valueOf(i); // Bad
  s = "a" + i; // Better
  return s;
}
