Add a New Method with a Return Variable

1. Create a new Android project, if you don't already have one.

2. In the MainActivity.java file, add the below code after the onCreate method. This will create a new method named myReturnMethod with an integer return value. This will return an integer value of 3.

private int myReturnMethod() {
    return 3;
}

3. Compile and run!
