});
this.setVisible(true);
this.addKeyListener(new KeyMonitor());
}
private class KeyMonitor extends KeyAdapter {
@Override
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();
if(key == KeyEvent.VK_UP) {
System.out.println("向上移动");
}
if(key == KeyEvent.VK_DOWN) {
System.out.println("向下移动");
}
if(key == KeyEvent.VK_LEFT) {
System.out.println("向左移动");
}
if(key == KeyEvent.VK_RIGHT) {
System.out.println("向右移动");

public static void main(String[] args) {
new test().lauch();
