作业一：请在草稿纸上手写一个单例模式的实现代码。
作业二：请用组合设计模式编写程序，打印输出图1的窗口。定义IComponent接口：
public interface IComponent {
	public void draw();
}
ComponentNode实现IComponent：
public class ComponentNode implements IComponent {
	private Vector<IComponent> childList;
	private String name;
	public ComponentNode(String name) {
		// TODO Auto-generated constructor stub
		childList = new Vector<>();
		this.name = name;
	}
	public void addChild(IComponent leaf) {
		childList.add(leaf);
	}
	@Override
	public void draw() {
		// TODO Auto-generated method stub
		System.out.println("print " + this.name);//广度优先输出
		for (IComponent iComponent : childList) {
			iComponent.draw();
		}
	}
}
ComponentLeaf实现IComponent：
public class ComponentLeaf implements IComponent {
	private String name;
	public ComponentLeaf(String name) {
		// TODO Auto-generated constructor stub
		this.name = name;
	}
	@Override
	public void draw() {
		// TODO Auto-generated method stub
		System.out.println(this.name);
	}
}
测试函数：
public class Test {
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ComponentNode winform = new ComponentNode("winform(window窗体)");
    
		ComponentNode frame = new ComponentNode("frame(FRAME1)");
		frame.addChild(new ComponentLeaf("label(用户名)"));
		frame.addChild(new ComponentLeaf("textbox(文本框)"));
		frame.addChild(new ComponentLeaf("label(密码)"));
		frame.addChild(new ComponentLeaf("passwordbox(密码框)"));
		frame.addChild(new ComponentLeaf("checkbox(复选框)"));
		frame.addChild(new ComponentLeaf("textbox(记住用户)"));
		frame.addChild(new ComponentLeaf("linkLabel(忘记密码)"));
		winform.addChild(new ComponentLeaf("picture(LOGO图片)"));
		winform.addChild(new ComponentLeaf("button(注册)"));
		winform.addChild(new ComponentLeaf("button(登录)"));
    
		winform.addChild(frame);
		winform.draw();
	}
}
输出结果：
