beginner trouble with window listener, nested if statements

[redpayne]

Ok-I am doing homework out of a book and the instructions are to display an interface with 5 option buttons in a frame. When clicked, each button changes the background color of the frame. It proceeds to tell me to construct CheckboxGroup, use FlowLayaout and add the Checkboxes to the frame along with ItemListener.
It says addWindowListen er()method, write code for itemStateChange d() which uses the getState() method and nested if statements.
--I am so stuck. I hate this book, it does not have any example close to this as to how to do it and I am so so stuck-PLEASE HELP!
This is how far I have gotten. Anything I have tried past this has not compiled.

import java.awt.*;
import java.awt.event.*;
 
public class ColorButtons extends Frame implements ItemListener
{
 
 
public static void main(String[] args)
{
}//end main arg
 
    //declare variables
    boolean answer = false;
 
    //construct CheckboxGroup
    CheckboxGroup sizeGroup = new CheckboxGroup();
    Checkbox BlueBox = new Checkbox("Blue", true, sizeGroup);
    Checkbox RedBox = new Checkbox("Red", false, sizeGroup);
    Checkbox YellowBox = new Checkbox("Yellow", false, sizeGroup);
    Checkbox PinkBox= new Checkbox("Pink", false, sizeGroup);
    Checkbox GrayBox = new Checkbox("Gray", false, sizeGroup);
 
    //add components
public void init()
{
        add(BlueBox);
        BlueBox.addItemListener(this);
        add(RedBox);
        RedBox.addItemListener(this);
        add(YellowBox);
        YellowBox.addItemListener(this);
        add(PinkBox);
        PinkBox.addItemListener(this);
        add(GrayBox);
           GrayBox.addItemListener(this);
 
 
}//end public void init
//this method is triggered by the user clicking an option button
public void itemStateChanged(ItemEvent choice)
{
 
}//end itemStateChanged
 
     //if statements
}//end public class

Im a little confused by what you have writen, try the HelloWorldFrame tatourial! it will help get you started. also, If you are looking for a good book try

Java A Beginners Guide by Hebert schilt! Its informative and has many examples!

Remeber you need to write a runable method in main!
