STEP 1

Return the number.

When the method should give a result, instead of void indicate the type of response. return returns the number to where it came from.

static int add(int a, int b) {
    return a + b;
}

✦ This method gets two numbers and gives the amount.

STEP 2

Show me the answer.

Call the method inside println. Java first calculates the answer, then shows it.

System.out.println(add(2, 3));

        System.out.println(add(2, 3));
    }
    static int add(int a, int b) {
        return a + b;
