Chapter 14, Problem 5FTE
Explanation of Solution
Given code:
private class MyMouseListener implements MouseListener
{
public void mouseClicked(MouseEvent e)
{
mouseClicked += 1;
}
}
Error in the given code:
In the given code, there are some errors. That is in implementing the interface.
- To implement “MyMouseListener” interface, the user have to implement all the five methods that include mouseClicked, mouseEntered, mouseExited, mousePressed, and mouseReleased.
- The user cannot implement one method only.
- For that purpose, the user have to use an adapter method.
- To implement “MyMouseListener” interface from “MouseAdapter”, the user can use the word “extends” instead of “implements”.
- Hence, the Line 1 should be replaced with “private class MyMouseListener extends MouseAdapter”.
Using adapter class:
- In Java API, an adapter class is another technique for creating a listener class...

toString() and equals() Methods
This lab will demonstrate how the toString() and equals() methods work when they are
not overridden. Type up the code and submit the BOTH results.
CODE
public class ObjectToString(
public static void main(String[] args) {
ClassOne co new ClassOne();
ClassTwo ct = new ClassTwo();
}
}
public class Classone {
System.out.println(co);
System.out.println(ct);
System.out.println(co.equals(ct));
public void printfle() {
System.out.println("I am from ClassOne");
}
public class ClassTwo (
public void printMe() {
}
System.out.println("I am from ClassTwo");
Run the program and notice the output.
