发布于: 2020 年 06 月 24 日
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。 
代码如下：

package com.example.demo;
﻿
public abstract class WinForm {
	private String name;
﻿
	public WinForm(String name) {
		this.name = name;
	}
﻿
	public WinForm(){}
﻿
	public String getName() {
		return name;
	}
﻿
	public void setName(String name) {
		this.name = name;
	}
﻿
	protected abstract void add(WinForm winForm);
﻿
	protected abstract void romove(WinForm winForm);
﻿
	protected abstract void display(int depth);
}
Frame.java
package com.example.demo;
﻿
import java.util.ArrayList;
import java.util.List;
﻿
public class Frame extends WinForm {
	private List<WinForm> cList;
	public Frame(){
		cList = new ArrayList<WinForm>();
	}
	public Frame(String name){
		super(name);
		cList = new ArrayList<WinForm>();
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
		cList.add(winForm);
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
		cList.remove(winForm);
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
		for (WinForm c : cList) {
			c.display(depth + 2);
		}
	}
}
Button.java

public class Button extends WinForm {
	public Button(String name){
		super(name);
	}
﻿

		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {

﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}

	public CheckBox(String name){
		super(name);
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}
Lable.java
package com.example.demo;
﻿
public class Lable extends WinForm {
	public Lable(String name){
		super(name);
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}
LinkLable.java
package com.example.demo;
﻿
public class LinkLable extends WinForm {
	public LinkLable(String name){
		super(name);
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}

package com.example.demo;
﻿
public class PasswordBox extends WinForm {
	public PasswordBox(String name){
		super(name);
	}
﻿
	@Override

		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override

Picture.java
package com.example.demo;
﻿
public class Picture extends WinForm {
	public Picture(String name){
		super(name);
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}
TextBox.java
package com.example.demo;
﻿
public class TextBox extends WinForm {
	public TextBox(String name){
		super(name);
	}
﻿
	@Override
	protected void add(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void romove(WinForm winForm) {
		// TODO Auto-generated method stub
﻿
	}
﻿
	@Override
	protected void display(int depth) {
		// TODO Auto-generated method stub
		StringBuilder sb = new StringBuilder("");
		for (int i = 0; i < depth; i++) {
			sb.append("-");
		}
		System.out.println(new String(sb) + this.getName());
	}
﻿
}
main代码
public static void main(String[] args) {
		WinForm root = new Frame();
		root.setName("WINDOW窗口");
		root.add(new Picture("Logo图片"));
		root.add(new Button("登录"));
		root.add(new Button("注册"));
﻿
		WinForm iFrame = new Frame("FRAME1");
		iFrame.add(new Lable("用户名"));
		iFrame.add(new TextBox("文本框"));
		iFrame.add(new Lable("密码"));
		iFrame.add(new PasswordBox("密码框"));
		iFrame.add(new CheckBox("复选框"));
		iFrame.add(new TextBox("记住用户名"));
		iFrame.add(new LinkLable("忘记密码"));
		root.add(iFrame);
		root.display(0);
}
运行结果：
WINDOW窗口
--Logo图片
--登录
--注册
--FRAME1
----用户名
----文本框
----密码
----密码框
----复选框
----记住用户名
----忘记密码
