February 14, 2009 at 8:23 PM

I can't use my code that I wrote it say Exception in thread "main" java.lang.NoClassDefFoundError: TextFieldTest/java

I was creating a JPassword and JTextField program at the very same time for my school's actual exam.. this is the code...

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;



public class TextFieldTest extends JFrame{

private JTextField text1,text2,text3;

private JPasswordField password;



public TextFieldTest(){

super("Testing JTextField and JPasswordField");

Container c=getContentPane();

c.setLayout(new FlowLayout());



text1=new JTextField(10);

c.add(text1);



text2=new JTextField("Enter Text Here!");

c.add(text2);



text3=new JTextField("Uneditable Text Field", 20);

text3.setEditable(false);

c.add(label3);



password=new JPasswordField("Hidden Text");

c.add(password);



TextFieldHandler handler=new TextFieldHandler();

text1.addActionListener(handler);

text2.addActionListener(handler);

text3.addActionListener(handler);

password.addActionListener(handler);



setSize(325,100);



show();

}

public static void main(String args[]){

TextFieldTest app=new TextFieldTest();



app.addWindowListener(

new WindowAdapter(){

public void windowClosing(WindowEvent e){

System.exit(0);

}

}

);

}

}



private class TextFieldHandler implements ActionListener{

public void actionPerformed(ActionEvent e){



String s="";



if(e.getSource()==text1)



s="text1:"+e.getActionCommand();



else if(e.getSource()==text2)



s="text2:"+e.getActionCommand();



else if(e.getSource()==text3)



s="text3:"+e.getActionCommand();



else if(e.getSource()==password)



JPasswordField pwd=(JPasswordField)e.getSource();



s="password:"+new String(pwd.getPassword());

}

JOptionPane.showMessageDialog(null, s);

}

}

}
