Chapter 8, Problem 2AW

Consider the following class declaration:

 public class Thing

 {

   private int x;

   private int y;

   private static int z = 0;

   public Thing()

   {

     x = z;

     y = z;

   }

   static void putThing(int a)

   {

     z = a;

   }

 }

Assume a program containing the class declaration defines three Thing objects with the following statements:

Thing one = new Thing();

Thing two = new Thing();

Thing three = new Thing();

1. a. How many separate instances of the x member exist?
2. b. How many separate instances of the y member exist?
3. c. How many separate instances of the z member exist?
4. d. What value will be stored in the x and y members of each object?
5. e. Write a statement that will call the putThing method.
