Week 2: Methods, strings and lists/5a Methods and return values

The method can also return a value. 
The return is done in the usual way with a return statement. 
The type of return value is specified in the method's header line: in practice, the empty return value type void is replaced by the return value type.



For example, a method that returns the sum of two integers (which is also an integer) would look like this:
public static int sum(int num1, int num2) {
    return num1 + num2;
}


Example method call:
public static void main(String[] args) {
   System.out.println(sum(4, 2));
   System.out.println(sum(10, 5 * 4));

   int result = sum(5, 15);
   System.out.println(result);
}
Program outputs:
