1 importjava.util.ArrayList;
2
3 publicclass H2ClassA {
4 ArrayList<H2ClassB> list = newArrayList<H2ClassB> ();
5
6 publicstaticvoid main (String args []) {
7 H2ClassA y = new H2ClassA ();
8 int [] v = {4, 3, 7, 5, 99, 3};
9 for (int m: v)
10 y.list.add (new H2ClassB (m));
11 System.out.println (y);
12 } // end main
13
14 } // end class H2ClassA
15
16 class H2ClassB {
17 int x;
18 H2ClassB (int a) { x = a;}
19 } // end H2ClassB
OUTPUT:
4 3 7 5 99 3

III. How can the following code be corrected? Give at least two good answers.

1 publicclass H2ClassC {
2 H2ClassC (int a) {}
3 }// end class H2ClassC
4
5 class H2ClassD extends H2ClassC{
6 } // end class H2ClassD

IV. Why does the following code give a compiler error? How should it be fixed?

1 publicclass H2ClassE {
2 int x, y, z;
3
4 H2ClassE (int a) {
5 x = a;
6 this (5, 12);
7 }
8
9 H2ClassE (int b, int c) {
10 y = b;
11 z = c;
12 }
13 } // end class H2ClassE

public static final intmyNumber = 17.36;

VI. What is wrong with the following code? How should it be fixed?

1 publicclass H2ClassG {
2 finalint x;
3
4 H2ClassG () {}
5 H2ClassG (int a) {x = a;}
6 }// end class H2ClassG

VII. What is wrong with the following code? How should it be fixed?

1 publicclass H2ClassH {
2 finalint x;
3
4 int H2ClassH () {
5 if (x == 7) return 1;
6 return 2;
7 }// end
8 } // end class H2ClassH

VII. What is wrong with the following code? x should be given a value of 24. What are two ways this can be legally accomplished?

1 publicclass H2ClassI {
2 finalint x;
3
4 publicstaticvoid main (String args []) {
5 H2ClassI h = new H2ClassI ();
6 h.x = 24;
7 }// end main
8 } // end class H2ClassI

IX. What is wrong with the following code? Give two effective ways to fix it.

1 importjavax.swing.*;
2 importjava.awt.event.*;
3
4 publicclass H2ClassJ extendsJFrame {
5 publicstaticfinallongserialVersionUID = 22;
6
7 public H2ClassJ () {
8 addMouseListener (newMouseListener () {
9 publicvoidmouseClicked (MouseEvent e) {}
10 });
11 } // end constructor
12
13 } // end class H2ClassJ

X. Why does the following code give a compiler warning? (Use javac -Xlint) How should it be fixed?
1 importjavax.swing.*;
2
3 publicclass H2ClassK {
4 String [] sa = {"a", "b", "c"};
