编写一个Java程序，利用鼠标事件监听，显示出鼠标在屏幕中点击的坐标位置

好的，您可以尝试如下代码：

import java.awt.*;
import java.awt.event.*;

public class MouseListenerDemo extends Frame implements MouseListener {

   private TextField tfMouseX; 
   private TextField tfMouseY; 

   public MouseListenerDemo() {
      setLayout(new FlowLayout()); 

      add(new Label("X-Click: ")); 

      tfMouseX = new TextField(10); 
      tfMouseX.setEditable(false); 
      add(tfMouseX); 

      add(new Label("Y-Click: ")); 

      tfMouseY = new TextField(10);
      tfMouseY.setEditable(false);  
      add(tfMouseY); 

      addMouseListener(this);
         

      setTitle("MouseListener Demo"); 
      setSize(350, 100); 
      setVisible(true);       
   }

   public static void main(String[] args) {
      new MouseListenerDemo(); 
   }

   @Override
   public void mouseClicked(MouseEvent evt) {
      tfMouseX.setText(evt.getX() + "");
      tfMouseY.setText(evt.getY() + "");
   }

   @Override public void mousePressed(MouseEvent evt) { }
   @Override public void mouseReleased(MouseEvent evt) { }
   @Override public void mouseEntered(MouseEvent evt) { }
   @Override public void mouseExited(MouseEvent evt) { }
}

这个程序利用鼠标事件监听器实现了监听用户鼠标点击的坐标位置，具体表现为，在程序窗口上单击鼠标，程序窗口上方将会显示该鼠标点击的（x,y）坐标。
