Consider a class Test that begins as follows:

public class Test

{

public static final int w = 1;

public static int x = 2;

private final int y = 3;

private int z = 4;

. . .

a. Which of w, x, y, and z—if any—can have their values changed by a constructor of Test? Why?

b. Which of w, x, y, and z—if any—can have their values changed by a client of Test? Why?
