Java – is it a best practice to create an unused reference to the value returned by the called method?
•
Java
I have a friend whose teacher thinks this is a good habit:
public void enterAnythingToContinue(){ String junk = in.nextLine(); }
I googled this, but couldn't find an explanation, although as expected, other users' method; Mainly teachers
It doesn't matter if you do, it's just a clear and pedagogical question?
Even if you don't have a definite answer, any input will be appreciated
Solution
It can point out the contradiction of methods in Java You can use this method like this
String junk = in.nextLine();
Or that
in.nextLine();
Maybe your teacher will emphasize a "function" rather than a "void return type" If you assign a value, the reader will know that you are using a method that returns a value
When you use a modern IDE, I don't see any advantages
