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);
}
}
}
