choice事件监听该怎么写?
如题 
 就是能给我一个完整的程序。。。 
------解决方案--------------------import java.awt.*; 
 import java.awt.event.*; 
 public class Tests implements ItemListener 
 { 
 	Choice choice; 
 	Frame f; 
 	TextArea text; 
 	public Tests() 
 	{ 
 		f = new Frame(); 
 		choice = new Choice(); 
 		for(int i= 1;i <10;i++) 
 		choice.add( "选项 " + i); 
 		choice.addItemListener(this); 
 		text = new TextArea(6,6); 
 		f.add(text, "Center "); 
 		f.add(choice, "North "); 
 		f.setSize(300,300); 
 		f.setVisible(true); 
 		f.addWindowListener(new WindowAdapter() 
 		                    { 
 		                      public void windowClosing(WindowEvent we) 
 		                      { 
 		                      	System.exit(0); 
 		                      } 
 		                      }); 
 	}  	 
 	public static void main(String args[]) 
 	{ 
 		new Tests(); 
 	}  	  	 
 	public void itemStateChanged(ItemEvent e) 
 	{  	    
 	   text.append(choice.getSelectedItem() +  '\n ' ); 
 	} 
 }   
 编译运行通过,参考下
