Swing Sample Code Not Working (Deitel's java)

[Zeke Hans]

Not to be an idiot about others, but I tried posting this question on stackoverflow, but all I got was a down vote, and got an answer about how my indentation was wrong. Ok I fixed that, but the code from the book still does not work. Make me kind of mad. In any case, hi ,new user! Here is my question:

// Fig. 14.6: LabelFrame.java 
// Demonstrating the JLabel class. 
import java.awt.FlowLayout; // specifies how components are arranged 
import javax.swing.JFrame; // provides basic window features 
import javax.swing.JLabel; // displays text and images 
import javax.swing.SwingConstants; // common constants used with Swing
import javax.swing.Icon; // interface used to manipulate images 
import javax.swing.ImageIcon; // loads images 

public class LabelFrame extends JFrame 
{ 
private JLabel label1; // JLabel with just text 

private JLabel label2; // JLabel constructed with text and icon 

private JLabel label3; // JLabel with added text and icon 

// LabelFrame constructor adds JLabels to JFrame 
public LabelFrame(){ 

super( "Testing JLabel" ); 

setLayout( new FlowLayout() ); 

// JLabel constructor with a string argument 

label1 = new JLabel( "Label with text" ); 

label1.setToolTipText( "This is label1" ); 

add( label1 ); 

//JLabel constructor with string, Icon and alignment arguments 

Icon bug = new ImageIcon( getClass().getResource( "bug1.png" ) ); 

label2 = new JLabel( "Label with text and icon", bug, 

SwingConstants.LEFT ); 

label2.setToolTipText( "This is label2" ); 

add( label2 ); 

label3 = new JLabel(); // JLabel constructor no arguments 

label3.setText( "Label with icon and text at bottom" ); 

label3.setIcon( bug ); // add icon to JLabel 

label3.setHorizontalTextPosition( SwingConstants.CENTER ); 

label3.setVerticalTextPosition( SwingConstants.BOTTOM ); 

label3.setToolTipText( "This is label3" ); 

add( label3 ); 
} 
} 

That was class one.

import javax.swing.JFrame; 

public class LabelTest 
{ 
public static void main( String[] args ) 
{ 
LabelFrame labelFrame = new LabelFrame(); // create LabelFrame 
labelFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); 
labelFrame.setSize( 260, 180 ); // set frame size 
labelFrame.setVisible( true ); // display frame 
} // end main 
} 

That was class two. I got this out of Deitel's java book. I am frustrated since I am new to Java, and this does not make sense. All I want to know is if the enclosed code in the attachment is right, or if it was a fail on my part inputting the code. Thank you. (I am using eclipse, and have the latest version of Java).

Hi Zeus,

Welcome to the ranch!

Can you tell us what you mean when you say the code doesnt work? what happens? what errors do you get? what does it do or not do that differs from your expectations?

[Stuie Clarky]

If you use Eclipse, does that give you any error messages?

Also with that textbook, I believe there is a site that you can download all the source code used in the examples from that is specified in the book somewhere (I don't have it to hand so I can't check). Also it might be worth checking the publishers site to see if there is any amendments/corrections that have been published.

Aside from that it is hard to help you when we don't know what the error is.

Edit: Also this person seems to also be having issues with the exercise, perhaps that will help you?
