本文提供了一个使用Java实现系统托盘程序的示例代码，包括如何创建托盘图标、设置弹出菜单以及处理鼠标点击事件等关键步骤。

测试代码包括2个文件: TaryFrame.java 和 Tary.java.

/////////////////////////////////////////////// 1. TaryFrame.java //////////////////////////////////////////////////////

import javax.swing.JFrame;

import javax.swing.JTextArea;
import javax.swing.JTextField;

public class TaryFrame extends JFrame{

public static JTextArea jta_info = new JTextArea(10,30);

public JTextField jtf_port;

public TaryFrame(){
  this.setTitle("tray test");
  this.setSize(410,380);

  this.setDefaultCloseOperation(EXIT_ON_CLOSE);

  //窗体大小固定
     setResizable(false);
     new Tary(this);
  this.setVisible(true);
}

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

}
