[Sarfaraj Khan]

Hello Guys,

I have one query to discuss with you. My query is related to the JMenuItem class of java. I am not getting the what is the use of JMenuItem class of java. I don't have any knowledge about it's methods and constructor declaration. If you posses sound knowledge about the JMenuItem class of java, then please let me know the same with proper example. Your help would be greatly appreciable.

A JMenuItem used for the implementation of an item in a menu. A menu item is essentially a button sitting in a list. When the user selects the "button", the action associated with the menu item is performed. A JMenuItem contained in a JPopupMenu performs exactly that function. This java class provides standard Look and Feel (L&F) renditions. This java class is basically extended from the 'javax.swing.AbstractButton' package.

Hi,

I recommend you to go through the following constructors of JMenuItem class of java:

1. JMenuItem(String text1, int nr)
2. JMenuItem(Action ac1)
3. JMenuItem(String text1, Icon icon1)
4. JMenuItem(String text1)
5. JMenuItem(Icon icon1)

Please following example of java, which will help you to know about the JMenuItem class:

import javax.swing.JMenuItem;
import javax.swing.KeyStroke;

public class JMenuItemDM {

  public static void main(final String args[]) {
    JFrame VO = new JFrame("MenuSample Example");
    VO.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JMenuBar menuBar = new JMenuBar();

    JMenu fileMenu = new JMenu("File");
    fileMenu.setMnemonic(KeyEvent.VK_F);
    menuBar.add(fileMenu);
    
    JMenuItem PMIT = new JMenuItem("Paste", KeyEvent.VK_P);
    KeyStroke ctrlVKeyStroke = KeyStroke.getKeyStroke("control V");
    PMIT.setAccelerator(ctrlVKeyStroke);
    PMIT.setEnabled(false);
    fileMenu.add(PMIT);

    VO.setJMenuBar(menuBar);
    VO.setSize(250, 250);
    VO.setVisible(true);
  }
}

Hello friend,

If you want to create separating Menu using JMenuItem class, then please review following java example:

import javax.swing.JMenuItem;
import javax.swing.JMenu;
import javax.swing.JSeparator;

public class JMIMain {
  public static void main(String[] argnv) throws Exception {
    JMenu menu03 = new JMenu("Menu Label");

    JMenuItem item01 = new JMenuItem("Item Label");
    menu03.add(item1);

    menu03.add(new JSeparator());

    JMenuItem item02 = new JMenuItem("Item Label");
    menu03.add(item02);
  }
}
