How to Set the Look and Feel (The Java™ Tutorials > Creating a GUI With JFC/Swing > Modifying the Look and Feel)

Thanks a lot for replying.
I saw the link and I already used
UIManager.setLookAndFeel(UIManager.getSystemLookAn dFeelClassName());
and
UIManager.setLookAndFeel("javax.swing.plaf.metal.M etalLookAndFeel");
but its not changed at all.
So can you please suggest me what else can be done.

If you need further help then you need to create a Short, Self Contained, Correct Example (SSCCE)
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

The code is

import java.awt.event.*;
import java.io.File;
import javax.swing.*;
public class CurveFitting extends JFrame implements ActionListener, FocusListener{

/**
* @param args
*/
public CurveFitting() throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException{
super("My GUI");
//code to add components
pack();
setVisible(true);
UIManager.setLookAndFeel("javax.swing.plaf.metal.M etalLookAndFeel");
setDefaultCloseOperation(javax.swing.WindowConstan ts.EXIT_ON_CLOSE);

}
p
public void actionPerformed(ActionEvent e) {
//to perfom some action
}

public static void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException {
// TODO Auto-generated method stub
CurveFitting cf=new CurveFitting();
}
}
but its not changing the appearance at all.

Doh, read the tutorial, especially the parts about how to set a look and feel after the GUI is visible, or when to set the L&F.

I saw and then I added the line
UIManager.setLookAndFeel("javax.swing.plaf.metal.M etalLookAndFeel");
And I'm not able to make out where I'm going wrong.
Give me some suggestion.

google
UIManager.setLookAndFeel

copy/paste/compile/run any of the numerous examples you'll find,
and if you can't work it out, seriously, apply to macdonalds

MetalLookAndFeel is by default.
try with some other look and feel, for example windows look and feel.

For example if you want Windows look and feel use this code:

try {
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
        } catch (Exception e) {
            e.printStackTrace();
