3.4 Methods — double then add one

Total: 0 / 3 pts

Practice mode — check each part and get hints as you go.

Task

Two helpers are written above. Fill in doubleThenAddOne so that it doubles n and then adds one — by calling both helpers.

For doubleThenAddOne(5) the program prints 11.

Your solution

public class Main {

    public static int doubleIt(int n) {
        return n * 2;
    }

    public static int addOne(int n) {
        return n + 1;
    }

    public static int doubleThenAddOne(int n) {
        // call doubleIt first, then addOne on that result

    }

    public static void main(String[] args) {
        System.out.println(doubleThenAddOne(5));
    }
}
