java 禁用按键的疑难问题

Question

现在我定义了一个JEditorPane
请问如何仅仅只在这个组件上禁用除了上,下,左,右之外的按键呢
不是全局的啊,是仅对改组件有效的另外请附上一个实例,不要说些无稽之谈的话谢谢大家了,感激不尽

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;import javax.swing.JEditorPane;
import javax.swing.JFrame;
public class A extends JFrame { public static void main(String[] args) {

A a = new A();

a.setVisible(true);

JEditorPane p = new JEditorPane();
a.add(p);

p.addKeyListener(new KeyListener() { @Override
public void keyPressed(KeyEvent arg0) {
int kc = arg0.getKeyCode();
if (kc == KeyEvent.VK_UP || 
kc == KeyEvent.VK_DOWN|| 
kc == KeyEvent.VK_LEFT|| 
kc ==KeyEvent.VK_RIGHT)
{
arg0.consume();
}

} @Override
public void keyReleased(KeyEvent arg0) {
int kc = arg0.getKeyCode();
if (kc == KeyEvent.VK_UP || 
kc == KeyEvent.VK_DOWN|| 
kc == KeyEvent.VK_LEFT|| 
kc ==KeyEvent.VK_RIGHT)
{
arg0.consume();
}

} @Override
public void keyTyped(KeyEvent arg0) {
int kc = arg0.getKeyCode();
if (kc == KeyEvent.VK_UP || 
kc == KeyEvent.VK_DOWN|| 
kc == KeyEvent.VK_LEFT|| 
kc ==KeyEvent.VK_RIGHT)
{
arg0.consume();
}

}

});

}
}
