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。

class Component {
    private Component(){}
    public Component(String title,String detail){
        this.title=title;
        this.detail=detail;
    }
    private String title;
    private String detail;
    private List<Component> componentList=new ArrayList<>();
    public void print() {
        System.out.printf("print %s(%s)\n",title,detail);
        for(Component obj:componentList){
            obj.print();
        }
    }
    public void addComponent(Component component) {
        this.componentList.add(component);
    }
}
public class Demo {
    public static void main(String[] args) {
        Component winForm = new Component("WinForm","WINDOW窗口");
        Component picture = new Component("Picture","LOGO图片");
        Component button1 = new Component("Button","登录");
        Component button2 = new Component("Button","注册");
        Component frame = new Component("Frame","FRAME1");
        Component lable1 = new Component("Lable","用户名");
        Component textBox1 = new Component("TextBox","文本框");
        Component lable2 = new Component("Lable","密码");
        Component passwordBox = new Component("PasswordBox","密码框");
        Component checkBox = new Component("CheckBox","复选框");
        Component textBox2 = new Component("TextBox","记住用户名");
        Component linkLable = new Component("LinkLable","忘记密码");
        winForm.addComponent(picture);
        winForm.addComponent(button1);
        winForm.addComponent(button2);
        winForm.addComponent(frame);
        frame.addComponent(lable1);
        frame.addComponent(textBox1);
        frame.addComponent(lable2);
        frame.addComponent(passwordBox);
        frame.addComponent(checkBox);
        frame.addComponent(textBox2);
        frame.addComponent(linkLable);
        winForm.print();
    }
}
