JPasswordField in Java Swing Example

The PasswordField is a special kind of textfield. It is a single line textfield used for accepting passwords without displaying the characters typed in. Each typed character is represented by an echo character typically an astriek (*). To create a PasswordField component, instantiate the JpasswordField class.

import javax.swing.*; 
 import java.awt.* ; 
 class JPasswordFieldExample extends JFrame 
 { 
      JPasswordFieldExample() 
     { 
         setLayout(new FlowLayout()); 
         JLabel lblUserid = new JLabel("Userid"); 
         JTextField txtUserid = new JTextField("Mr Thakur",15); 
         JLabel lblpassword = new JLabel("password"); 
         JPasswordField txtpassword = new JPasswordField(15); 
         add(lblUserid); add(txtUserid); 
         add(lblpassword); add(txtpassword); 
     } 
 } 
  class JPasswordFieldJavaExample 
  { 
        public static void main(String args[]) 
       {  
            JPasswordFieldExample frame = new JPasswordFieldExample(); 
            frame.setTitle("JPasswordField in Java Swing Example"); 
            frame.setBounds(200,250,250,150); 
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
            frame.setVisible(true); 
      } 
 }
