returning a value from a method to another method

Question

Can somebody tell me why the value returned is 3 and not 8. Doesn\'t the return x statement from the addFive method change the value of x

Answer 1

You are calling the method addFive(int x) with x, but not assigning the returned value to anything. So, inside main()'s scope x remains as before, 3 - which is what is being printed. So, you can either store the returned value to x itself:

x = addFive(x);

or make the function call within print statement:

System.out.println("x = " + addFive(x));
