Design Login And Dashboard Form In Java Netbeans
In this Java Tutorial we will see How To Design A Login Form And A Dashboard Form 
In Java NetBeans .

In This Java Swing Design Tutorial We Will Use:
- Java Programming Language.
- Netbeans IDE.
- flatuicolorpicker.com = to get flat colors.
- iconsdb.com = to get icons.
- canva.com = to get the app logo.



Project Description And Source Code:

1 - The Login Form

        // display the login form in the center of the screen
        this.setLocationRelativeTo(null);
        
        // set icons
        jLabel_close.setIcon(new javax.swing.ImageIcon(getClass().getResource("../IMAGES/x.png")));
        jLabel_user.setIcon(new javax.swing.ImageIcon(getClass().getResource("../IMAGES/user.png")));
        jLabel_pass.setIcon(new javax.swing.ImageIcon(getClass().getResource("../IMAGES/lock.png")));
        jLabel_showPass.setIcon(new javax.swing.ImageIcon(getClass().getResource("../IMAGES/eye.png")));
        jLabel_up.setIcon(new javax.swing.ImageIcon(getClass().getResource("../IMAGES/up.png")));
        
        // set borders
        Border panelBorder = BorderFactory.createMatteBorder(0, 0, 0, 5, Color.black);
        jPanel_container.setBorder(panelBorder);
        
        Border titleBorder = BorderFactory.createMatteBorder(0, 0, 4, 0, Color.gray);
        jLabel_title.setBorder(titleBorder);    

Java Login Form Design

// checkbox to show and hide the password

        }
        // hide password chars
        else
        {
            jPasswordField_password.setEchoChar('*');
        }
    }


Java Login Form Design

// jlabel to close the form

        // close this form
        this.dispose();

            if(jPanel_message.getHeight() != 0)
            {
               jPanel_message.setBounds(jPanel_message.getX(), jPanel_message.getY(), jPanel_message.getWidth(), jPanel_message.getHeight() - 5);

            {
               jPanel_message.setBounds(jPanel_message.getX(), jPanel_message.getY(), jPanel_message.getWidth(), jPanel_message.getHeight() + 5);
            }
            else
            {
                timerDown.stop();
            }
        }
    });

Java Login Form Design

// the login button
    private void jButton_loginActionPerformed(java.awt.event.ActionEvent evt) {
