Your first method

Now write a method. Don't write main — the checker calls your method with several inputs and checks what you return. Complete twice so it returns n times two.

Complete twice(int n) so it returns n times two. Don't write main.

public class Num {
    public static int twice(int n) {
        return 0;   // change this
    }
}
