AddEmptyString


AddEmptyString
Finds empty string literals which are being added. This is an inefficient way 
to convert any type to a String.
        
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                         
//AdditiveExpression/PrimaryExpression/PrimaryPrefix/Literal[@Image='""']
                
                
  
		    
		    
	    
	    
        
        
        Example:
            
                    
             
        String s = "" + 123; // bad 
        String t = Integer.toString(456); // ok
