Answer:
We are deriving two classes from GameShape parent class.
We are creating objects for playerpiece, tilepiece classes.
We are assigning playerpiece objects to its parent class GameShape. So, now shape reference has the ability to access only parent class method and variable.
So the output would be "displaying shape" for doShapes(player).
The output for doShapes(tile) is also "displaying shape".

Use the classes given in the previous question and write the output tha t is generated when this program is run. You may write your answer as "Elaine 2 Jerry 1" or "Compiler Error" or "Runtime Error" If there is an error then explain why. public class Main{ public static void main(String args[]){ Object o = new Kramer(); ((George)(o)).method1(); ((Jerry)(o)). method1(); 0.method2(); public class George extends Elaine {! public void method1() { System.out.print("George 1 "); public class Jerry {...

Exercise 1): take the program “InteractiveCounting” (attached). Your task is to change the implementation of both the “ReadInput” and the “Count” classes. Currently these classes extends Thread. You should now use the Runnable interface to implement the thread. The output of the program should not change. I have also attached the class ThreadType2 to give you a working example on how to implement a thread using the Runnable interfacethe program is here package threadExamples; import java.util.Scanner; public class InteractiveCounting {...
