How to add JRadioButtonMenuItem in Java

Let’s say we have a menu and within that we need to set the JRadioButtonMenuItem. Here’s the Menu −

JMenu editMenu = new JMenu("Edit");
editMenu.setMnemonic(KeyEvent.VK_E);
menuBar.add(editMenu);

Now, set the editMenu and add it to the MenuBar −

JMenu editMenu = new JMenu("Edit");
editMenu.setMnemonic(KeyEvent.VK_E);
menuBar.add(editMenu);

Now, create Options Menu and add it to the editMenu −

JMenu optionsMenu = new JMenu("Options");
optionsMenu.setMnemonic(KeyEvent.VK_O);
editMenu.add(optionsMenu);

Now, set the JRadioButtonMenuItem and add it to the editMenu created above −

ButtonGroup group = new ButtonGroup();
JRadioButtonMenuItem radioMenuItem = new JRadioButtonMenuItem("SmartInsertMode", true);
radioMenuItem.setMnemonic(KeyEvent.VK_I);
optionsMenu.add(radioMenuItem);
group.add(radioMenuItem);
JRadioButtonMenuItem radioMenuItem2 = new JRadioButtonMenuItem("SmartDeleteMode");
radioMenuItem.setMnemonic(KeyEvent.VK_D);
optionsMenu.add(radioMenuItem2);
group.add(radioMenuItem2);

The following is an example add JRadioButtonMenuItem in Java −
