Answer 1

试试这个：

menuItem.setAccelerator(KeyStroke.getKeyStroke(
    java.awt.event.KeyEvent.VK_S, 
    java.awt.Event.CTRL_MASK));

其中VK_S是您想要的密钥，CTRL_MASK是控制密钥。

使用

还有另一种选择

menuItem.setMnemonic('F');

如果您在运行程序时按ALT + F

，这将有效

仅供DELETE使用

jMenuItem1.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_DELETE, 0));
