1. Consider the following two classes:
public class ClassA {
    public void methodOne(int i) {
    }
    public void methodTwo(int i) {
    }
    public static void methodThree(int i) {
    }
    public static void methodFour(int i) {
    }
}
public class ClassB extends ClassA {
    public static void methodOne(int i) {
    }
    public void methodTwo(int i) {
    }
    public void methodThree(int i) {
    }
    public static void methodFour(int i) {
    }
}
a. Which method overrides a method in the superclass?
b. Which method hides a method in the superclass?
c. What do the other methods do?
2. Consider the 
Card, 
Deck, and 
DisplayDeck classes you wrote in 
Questions and Exercises: Classes. What Object methods should each of these classes override?
1. Write the implementations for the methods that you answered in question 2.
