Is there any benefit to returning the result of assigning a value to a local variable rather than the value directly?

Question

I am doing a java code inspection. Here is a function (snippet):

String getValue() {
     String res;
     StringBuilder strBuilder = new StringBuilder();

         


        

Answer 1

res is not used, so there is no reason to return like that. You can remove it:

String getValue() {
     StringBuilder bs = new StringBuilder();
     //
     // More code here that sets sb

     return bs.toString();
}
