The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases.
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.
