Importing the Java API into basic programs

Question

How do I import the API that comes with the JDK1.3 into my programs ? Is it a case of simply import java.api.*; ??
Does the new 1.3 version of the compiler include a Javabook which can be imported into programs. I have a text book which has sample programs which import Javabook. When I come to compile them, the compiler reports that Javabook is not known. Is Javabook from an earler version of the java compiler ?

It depends on what you want to do just as an example if you wanted to create a window app with a textfield you would need to import the necessary classes. Here is a sample of a JFrame with a text field:
import javax.swing.*;
import java.awt.*;
public class Frame1 extends JFrame
BorderLayout borderLayout1 = new BorderLayout();
JPanel jPanel1 = new JPanel();
JTextField jTextField1 = new JTextField();
public Frame1()
super();
try
jbInit();
catch (Exception e)
e.printStackTrace();
private void jbInit() throws Exception
this.getContentPane().setLayout(borderLayout1);
this.setSize(new Dimension(400, 300));
jTextField1.setText("jTextField1");
this.getContentPane().add(jPanel1, BorderLayout.CENTER);
jPanel1.add(jTextField1, null);
Note the import statements of java.awt.*; and javax.swing.*; this tells the compiler the to look for all the files needed to create this frame. The compiler already knows what it needs from the API, you just have to tell it where to look.
In short JavaBook should either come with the book on CD ROM or you have to download it from the publisher. Also check and see what files you need to import and use the import statement to point to the file that it needs: for example
import JavaBook.*;
Hope this helps
