Add 3 JLabels(Edit Text: Login Form, Username, Password)
Add 1 JTextField and 1 JPasswordField(Change Variable Name: tfUsername, pfPassword)
Add 2 JButtons(Edit Text: Login, Reset. Change Variable Name: bLogin, bReset)
Add 1 JCheckBox(Edit Text: Remember Password. Change Variable Name: chkRemember)
Add 1 JLabel(Change Variable Name: lMessage)

Format of Login Form Label: Font – Tahoma 24, Bold. Foreground – 0,0,255

Code:

private void bLoginActionPerformed(java.awt.event.ActionEvent evt) {                                      

       if (tfUsername.getText().equalsIgnoreCase("admin") && pfPassword.getText().equalsIgnoreCase("admin"))

       {

           if (chkRemember.isSelected())

           {

               lMessage.setText("Login Successfull with remembering option");

              

           }

           else

           {

           lMessage.setText("Login Successfull without remembering option");   

           }

       }

       else

       {

           lMessage.setText("Login Failed!");

       }

    }                                     

    private void bResetActionPerformed(java.awt.event.ActionEvent evt) {                                       

        tfUsername.setText(null);

        pfPassword.setText(null);

        lMessage.setText(null);

        chkRemember.setSelected(false);
