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。
﻿
﻿
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。
﻿
﻿
作业结果设计包含类:
Button 按钮类
CheckBox 单选框类
Form 窗体类
Frame 窗体架构类
Label 标签类
LinkLabel 链接标签类
PasswordBox 密码框类
PictureBox 图片框类
TextBox 文本框类
Window 窗体接口
Container 窗体容器接口
类图:
因为类图中元素过多, 只画出了部分类的关系, 剩下没在图中出现的类均实现 Window 接口, 结构和 Label 类类似。
Window 接口代码
public interface Window {
    void draw();
}
Container 接口代码
public interface Container {
    void addWindow(Window window);
}
Form 类代码
public class Form implements Window, Container {
    private final List<Window> childWindows;
    private final String name;
    public Form(String name) {
        this.childWindows = new ArrayList<>();
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("Print WinForm(%s)", name));
        childWindows.forEach(Window::draw);
    }
    @Override
    public void addWindow(Window window) {
        this.childWindows.add(window);
    }
}
Frame 类代码
public class Frame implements Window, Container {
    final private String name;
    final private List<Window> childWindows;
    public Frame(String name) {
        this.name = name;
        this.childWindows = new ArrayList<>();
    }
    @Override
    public void draw() {
        System.out.println(String.format("print Frame(%s)", name));
        this.childWindows.forEach(Window::draw);
    }
    @Override
    public void addWindow(Window window) {
        this.childWindows.add(window);
    }
}
Button 类代码
public class Button implements Window {
    final private String name;
    public Button(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print Button(%s)", name));
    }
}
CheckBox 类代码
public class CheckBox implements Window {
    final String name;
    public CheckBox(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print CheckBox(%s)", name));
    }
}
Label 类代码
public class Label implements Window {
    final String name;
    public Label(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print Label(%s)", name));
    }
}
LinkLabel 类代码
public class LinkLabel implements Window {
    final String name;
    public LinkLabel(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print LinkLabel(%s)", name));
    }
}
Password 类代码
public class PasswordBox implements Window {
    final String name;
    public PasswordBox(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print PasswordBox(%s)", name));
    }
}
PictureBox 类代码
public class PictureBox implements Window {
    final private String name;
    public PictureBox(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print Picture(%s)", name));
    }
}
TextBox 类代码
public class TextBox implements Window {
    final private String name;
    public TextBox(String name) {
        this.name = name;
    }
    @Override
    public void draw() {
        System.out.println(String.format("print TextBox(%s)", name));
    }
}
执行入口类代码
public class WinForm {
    public static void main(String[] args) {
        Form winForm = new Form("WINDOW 窗口");
        winForm.addWindow(new PictureBox("LOGO 图片"));
        winForm.addWindow(new Button("登录"));
        winForm.addWindow(new Button("注册"));
        Frame frame = new Frame("FRAME1");
        frame.addWindow(new Label("用户名"));
        frame.addWindow(new TextBox("文本框"));
        frame.addWindow(new Label("密码"));
        frame.addWindow(new PasswordBox("密码框"));
        frame.addWindow(new CheckBox("复选框"));
        frame.addWindow(new TextBox("记住用户名"));
        frame.addWindow(new LinkLabel("忘记密码"));
        winForm.addWindow(frame);
        winForm.draw();
    }
}
运行结果
Print WinForm(WINDOW 窗口)
print Picture(LOGO 图片)
print Button(登录)
print Button(注册)
print Frame(FRAME1)
print Label(用户名)
print TextBox(文本框)
print Label(密码)
print PasswordBox(密码框)
print CheckBox(复选框)
print TextBox(记住用户名)
print LinkLabel(忘记密码)
