结果如下，写的有些复杂了

private static ListTray mergeTrays(ListTray list) {

        MapInteger, ListGoods trayMap = new HashMap();

        ListTray newTray = new ArrayList();

        for (Tray tray : list) {

            ListGoods goods = tray.goods;

            if (trayMap.containsKey(id)) {

                // 将相同托盘id的商品放在一起

在JAVA中如何搞定托盘

JDK1.5以前用第三方插件，比如:systray4j

JDK1.5开始java自带托盘了，常见:SystemTray tray=SystemTray.getSystemTray(); // 获得本操作系统托盘的实例

Java做日历，日历格式参考Windows系统托盘的日期和时间程序。

import java.text.DateFormat;

import java.text.ParseException;

import java.util.Calendar;

import java.util.Date;

import java.util.GregorianCalendar;

import java.util.Scanner;

public class Game {

public void theCalendar(String str) throws ParseException {

Date date = DateFormat.getDateInstance().parse(str);

Calendar c = new GregorianCalendar();

c.setTime(date);

int year = c.get(Calendar.YEAR); // 返回年

int month = c.get(Calendar.MONTH); // 返回月

int today = c.get(Calendar.DAY_OF_MONTH);// 返回日

System.out.println("日\t一\t二\t三\t四\t五\t六");

c.set(Calendar.DAY_OF_MONTH, 1); //把当前日期设置为1号

int a = c.get(Calendar.DAY_OF_WEEK);//返回当前月份1号是星期几

for(int i=1; ia; i++) {

System.out.print("\t");

}

while(c.get(Calendar.MONTH) == month) {

if(c.get(Calendar.DAY_OF_MONTH) == today) {

System.out.printf("%2d●\t", c.get(Calendar.DAY_OF_MONTH));

} else {

System.out.printf("%2d\t", c.get(Calendar.DAY_OF_MONTH));

}

if(c.get(Calendar.DAY_OF_WEEK) == 7) {

System.out.println();

}

c.add(Calendar.DAY_OF_MONTH, 1);

}

}

public static void main(String[] args) throws ParseException {

Scanner sc = new Scanner(System.in);

System.out.println("请按照如下格式输入字符串1990-09-07");

String str = sc.nextLine();

new Game().theCalendar(str);

}

}

TrayIcon trayIcon;//

托盘图标，但不是

Image

类型的

哦

SystemTray Tray;//

系统托盘

Image

img=(new

ImageIcon("images/icon.png")).getImage();//

托盘图标，建

议使用较小的图片

public MyTray(){

final JFrame frame=new JFrame();

JPanel jp=new JPanel();

frame.add(jp);

frame.setSize(320,240);

frame.setLocationRelativeTo(null);

frame.setResizable(false);

frame.setIconImage(img);//

设置窗口左上角的图标

frame.setVisible(true);

Tray=SystemTray.getSystemTray();//

获得系统托盘实例

//

创建系统托盘的右键弹出菜单

PopupMenu pm=new PopupMenu();

MenuItem mi0=new MenuItem("Open");

MenuItem mi1=new MenuItem("Close");

pm.add(mi0);

pm.add(mi1);

trayIcon=new TrayIcon(img,"",pm);//

创建托盘图标实例

trayIcon.setImageAutoSize(true);//

图标自动适应托盘，也就是说它自动

改变大小

trayIcon.setToolTip(" ");//

设置提示语

//

添加系统托盘图标

frame.addWindowListener(new

WindowAdapter()

{//

当“关闭”窗口时，最

小化到系统托盘

public void windowClosing(WindowEvent e) {

try {

Tray.add(trayIcon);

} catch (AWTException exc) {

exc.printStackTrace();

}

}});

mi0.addActionListener(new ActionListener(){ //

右键弹出菜单的事件

监听

public void actionPerformed(ActionEvent e) {

frame.setExtendedState(JFrame.NORMAL);

frame.setVisible(true);

Tray.remove(trayIcon);

}

});

mi1.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

System.exit(0);

Tray.remove(trayIcon);//

退出程序，移出系统托盘处的图标
