Consider the following method.

public static void message(int a, int b, int c)
{
    if (a < 10)
    {
        if (b < 10)
        {
            System.out.print("X");
        }
        System.out.print("Y");
    }
    if (c < 10)
    {
        if (b > 10)
        {
            System.out.print("Y");
        }
        else
        {
            System.out.print("Z");
        }
    }
}

What is printed as a result of the call message(5, 15, 5)?
