+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);
+}
