1. 请在草稿纸上手写一个单例模式的实现代码，拍照提交作业。
﻿
2. 请用组合设计模式编写程序，打印输出图 1 的窗口，窗口组件的树结构如图 2 所示，打印输出示例参考图 3。

public class GenerateWindow {
    public static void main(String[] args){
        WinFrom winFrom = new WinFrom("WINDOW窗口");
        winFrom.add(new Picture("LOGO图片"));
        winFrom.add(new Button("登陆"));
        winFrom.add(new Button("注册"));
        Frame frame1 = new Frame("FRAME1");
        frame1.add(new Lable("用户名"));
        frame1.add(new TextBox("输入框"));
        frame1.add(new Lable("密码"));
        frame1.add(new PasswordBox("密码框"));
        frame1.add(new CheckBox("复选框"));
        frame1.add(new TextBox("记住密码"));
        frame1.add(new LinkLable("忘记密码"));
        winFrom.add(frame1);
