AddEmptyString

AddEmptyString

The conversion of literals to strings by concatenating them with empty strings is inefficient. It is much better to use one of the type-specific toString() methods instead.


                     
//AdditiveExpression/PrimaryExpression/PrimaryPrefix/Literal[@Image='""']
                

Example(s):


             
String s = "" + 123; 				// inefficient 
String t = Integer.toString(456); 	// preferred approach
