This little tool introduced in this paper mainly USES MouseInfo to obtain real-time information of the mouse, and then displays it on JDialog. Hope the following content is introduced, can let you know more about how to get the mouse coordinates on the screen, 1 up to learn it.

The code is as follows:

import java.awt.BorderLayout;
import java.awt.FlowLayout;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;

import javax.swing.border.EmptyBorder;
import javax.swing.JLabel;
import java.awt.Font;
import java.awt.Point;
import java.util.Timer;
import java.util.TimerTask;
import java.awt.Color;

public class MouseInfo extends JFrame {

  private final JPanel contentPanel = new JPanel();
  JLabel value_x = null;
  JLabel value_y = null;

  /**
   * Launch the application.
   */
  public static void main(String[] args) {
    try {
      MouseInfo info_frame = new MouseInfo();
      info_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      info_frame.setVisible(true);
      info_frame.setAlwaysOnTop(true);
      Timer timer = new Timer();
      timer.schedule(new TimerTask() {
        @Override
        public void run() {
          Point point = java.awt.MouseInfo.getPointerInfo().getLocation();
          // System.out.println("Location:x=" + point.x + ", y=" +
          // point.y);
          info_frame.value_x.setText("" + point.x);
          info_frame.value_y.setText("" + point.y);
        }
      }, 100, 100);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

  /**
   * Create the dialog.
   */
  public MouseInfo() {
    setTitle("\u9F20\u6807\u5750\u6807\u83B7\u53D6\u5668");
    setBounds(100, 100, 217, 156);
    getContentPane().setLayout(new BorderLayout());
    contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));
    getContentPane().add(contentPanel, BorderLayout.CENTER);
    contentPanel.setLayout(null);

    JLabel lblx = new JLabel("\u5750\u6807x:");
    lblx.setFont(new Font(" Song typeface ", Font.PLAIN, 15));
    lblx.setBounds(22, 27, 66, 31);
    contentPanel.add(lblx);

    JLabel lbly = new JLabel("\u5750\u6807y:");
    lbly.setFont(new Font(" Song typeface ", Font.PLAIN, 15));
    lbly.setBounds(22, 68, 66, 31);
    contentPanel.add(lbly);

    value_x = new JLabel("0");
    value_x.setForeground(Color.BLUE);
    value_x.setFont(new Font(" Song typeface ", Font.PLAIN, 20));
    value_x.setBounds(82, 27, 66, 31);
    contentPanel.add(value_x);

    value_y = new JLabel("0");
    value_y.setForeground(Color.BLUE);
    value_y.setFont(new Font(" Song typeface ", Font.PLAIN, 20));
    value_y.setBounds(82, 68, 66, 31);
    contentPanel.add(value_y);
  }
}
