The Separator divides the menu items in a separate group like same types of menu Items are divided into a individual parts. This program shows how to create menu bar, menus, submenus and Separators. Here, all items shows on a frame with the help of following methods and APIs JMenuBar, JMenu (String), JMenuItem (String). JMenuBar is the class which constructs a menu bar that contains several menus. JMenu (String) is the constructor of JMenu class. This constructor constructs the new menu. It takes the string type value which is the name label for the menu. JMenuItem (String) is the constructor of JMenuItem class which constructs new menu items for the specific menu. It takes string types value which is the label for the menu item.

import javax.swing.*; public class SwingMenu{ public static void main(String[] args) { SwingMenu s = new SwingMenu(); } public SwingMenu(){ JFrame frame = new JFrame("Creating a JMenuBar Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JMenuBar menubar = new JMenuBar(); JMenu filemenu = new JMenu("File"); filemenu.add(new JSeparator()); JMenu editmenu = new JMenu("Edit"); editmenu.add(new JSeparator()); JMenuItem fileItem1 = new JMenuItem("New"); JMenuItem fileItem2 = new JMenuItem("Open"); JMenuItem fileItem3 = new JMenuItem("Close"); fileItem3.add(new JSeparator()); JMenuItem fileItem4 = new JMenuItem("Save"); JMenuItem editItem1 = new JMenuItem("Cut"); JMenuItem editItem2 = new JMenuItem("Copy"); editItem2.add(new JSeparator()); JMenuItem editItem3 = new JMenuItem("Paste"); JMenuItem editItem4 = new JMenuItem("Insert"); filemenu.add(fileItem1); filemenu.add(fileItem2); filemenu.add(fileItem3); filemenu.add(fileItem4); editmenu.add(editItem1); editmenu.add(editItem2); editmenu.add(editItem3); editmenu.add(editItem4); menubar.add(filemenu); menubar.add(editmenu); frame.setJMenuBar(menubar); frame.setSize(400,400); frame.setVisible(true); } }
