简单,加个监听器就行。
jframe.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (KeyEvent.VK_0 <= e.getKeyCode() && e.getKeyCode() <= KeyEvent.VK_0) {
// 数字键 do something
} else if (e.getKeyCode() == KeyEvent.VK_PERIOD) {
// “.”号键 do something
} else if (e.getKeyCode() == KeyEvent.VK_PLUS) {
// “+”号键 do something
} else if (e.getKeyCode() == KeyEvent.VK_MINUS) {
// “-”号键 do something
} else if (e.getKeyCode() == KeyEvent.VK_MULTIPLY) {
// “*”号键 do something
} else if (e.getKeyCode() == KeyEvent.VK_SLASH) {
// “/”号键 do something
} else if (e.getKeyCode() == KeyEvent.VK_EQUALS) {
// “=”号键 do something
}
}
});
