Membuat Form Login dengan muncul Frame baru dan didalamnya ada menuBar
Pertama buat dulu class Utama,didalamnya terdapat form login
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
public class Utama {
   public static void main(String[] args) {
JFrame utama = new JFrame("Menu Utama");
utama.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
utama.setSize(new Dimension(300,150));
utama.setLocationRelativeTo(null);
utama.setLayout(new FlowLayout());
JLabel nama = new JLabel("Nama        : ");
JLabel password = new JLabel("Password : ");
final JTextField isinama = new JTextField(15);
final JPasswordField isipassword = new JPasswordField(15);
JButton buttonlogin = new JButton("Login");
buttonlogin.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
String unama = isinama.getText();
@SuppressWarnings("deprecation")
String pass = isipassword.getText();
if (unama.equals("ina") && pass.equals("meyta")) {
JOptionPane.showMessageDialog(null,
"Selamat Datang Anda Berhasil Login");
isinama.setText("");
isipassword.setText("");
isinama.requestFocus();
Menu m = new Menu();
} else {
JOptionPane.showMessageDialog(null,
"Nama dan Password Anda salah, silahkan ulangi");
isinama.setText("");
isipassword.setText("");
isinama.requestFocus();
}
}
});
JButton buttonreset = new JButton("Reset");
buttonreset.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
isinama.setText("");
isipassword.setText("");
isinama.requestFocus();
}
});
utama.add(nama);
utama.add(isinama);
utama.add(password);
utama.add(isipassword);
utama.add(buttonlogin);
utama.add(buttonreset);
utama.setVisible(true);
}
}

Kemudian Buat class Menu

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.FlowLayout;

import java.awt.Font;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;

import javax.swing.JScrollPane;

import javax.swing.JTextArea;

import javax.swing.ScrollPaneConstants;

public class Menu {

public Menu() {

final JFrame frame2 = new JFrame("Menu");

frame2.setSize(320, 250);

frame2.setLocationRelativeTo(null);

frame2.setLayout(new FlowLayout(FlowLayout.LEFT));

final JMenuBar bar = new JMenuBar();

JMenu menuhome = new JMenu("Beranda");

bar.add(menuhome);

JMenuItem itemaccount = new JMenuItem("Pengaturan Account");

menuhome.add(itemaccount);

menuhome.addSeparator();

JMenuItem itemLogout = new JMenuItem("Logout");

itemLogout.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

int pesan = JOptionPane.showConfirmDialog(null,

"Keluar aplikasi?", "Peringatan",

JOptionPane.YES_NO_OPTION);

if (pesan == 0)

// System.exit(0);

// System.out.println("logout...");

frame2.setVisible(false);

}

});

menuhome.add(itemLogout);

JMenu menuprof = new JMenu("Profil");

bar.add(menuprof);

final JMenuItem menuabout = new JMenu("About as");

menuprof.add(menuabout);

JMenuItem itemgambar = new JMenuItem("Gambar");

itemgambar.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent arg0) {

MenuGambar mg = new MenuGambar();

}

});

menuabout.add(itemgambar);

final JMenuItem iteminfo = new JMenuItem("Info");

iteminfo.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent arg0) {

String isiinfo = ("PIS1002 adalah nama kelas di Politeknik Telkom , didalamnya terdiri dari orang-orang "

+ "yang berasal dari berbagai kota. Memiliki karakter yang berbeda-beda dari orang-orang "

+ "yang berasal dari berbagai kota. Memiliki karakter yang berbeda-beda dari orang-orang "

+ "yang berasal dari berbagai kota. Memiliki karakter yang berbeda-beda dari orang-orang "

+ "yang berasal dari berbagai kota. Memiliki karakter yang berbeda-beda ");

JTextArea info = new JTextArea(isiinfo, 5, 30);

JScrollPane scroll = new JScrollPane(info,

ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,

ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);

info.setLineWrap(true);

info.setWrapStyleWord(true);

info.setForeground(Color.BLUE);

info.setFont(new Font("Papyrus", Font.ITALIC, 12));

//frame2.add(iteminfo);

// frame2.add(info);

frame2.add(scroll, BorderLayout.CENTER);

frame2.setVisible(true);

}

});

menuabout.add(iteminfo);

JMenu menuSearch = new JMenu("Pencarian");

bar.add(menuSearch);

JMenuItem itemnama = new JMenuItem("Nama");

menuSearch.add(itemnama);

menuSearch.addSeparator();

JMenuItem itememail = new JMenuItem("E-mail");

menuSearch.add(itememail);

// JMenuItem java = new JMenuItem("Java Project");

//String t ="Java Project";

//baru.add(new JMenuItem(t));

frame2.add(bar);

frame2.setVisible(true);

}

public static void main(String[] args) {

Menu m = new Menu();

}

}

Kemudian membuat class menu gambar

import java.awt.FlowLayout;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.SwingConstants;

public class MenuGambar {

public MenuGambar() {

final JFrame frameprof = new JFrame("Profil");

frameprof.setSize(800, 650);

frameprof.setLocationRelativeTo(null);

frameprof.setLayout(new FlowLayout());

ImageIcon gambar = new ImageIcon("PIs1002.gif");

JLabel lgambar = new JLabel("PIS1002", gambar, SwingConstants.CENTER);

frameprof.add(lgambar);

frameprof.setVisible(true);

}

public static void main(String[] args) {

MenuGambar mg = new MenuGambar();

}

}
