使用多线程完成洗菜、切菜、炒菜、上菜操作

要求：总共有3种菜,上菜必须等所有的菜都炒完才能上菜。

上菜ShangCai

package Homework;

public class Shangcai extends Thread {
	@Override
	public void run() {
		for (int i = 1; i < 4; i++) {
			System.out.println("上第" + i + "个菜");
			try {
				this.sleep(100);
				System.out.println("第" + i + "个菜上完");
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
}

炒菜操作ChaoCai

package Homework;

public class Chaocai extends Thread {
	@Override
	public void run() {
		try {
			this.sleep(700);
		} catch (InterruptedException e1) {
			e1.printStackTrace();
		}
		for (int i = 1; i < 4; i++) {
			System.out.println("开始炒第" + i + "个菜");
			try {
				this.sleep(500);
				System.out.println("第" + i + "个菜炒完了");
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
}

切菜操作：QieCai

package Homework;

public class Qiecai extends Thread {
	@Override
	public void run() {
		for (int i = 1; i < 4; i++) {
			try {
				this.sleep(350);
			} catch (InterruptedException e1) {
				e1.printStackTrace();
			}
			System.out.println("正在切第" + i + "个菜");
			try {
				this.sleep(200);
				System.out.println("第" + i + "个菜切完了");
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
}

洗菜操作洗菜：

package Homework;

public class Xicai extends Thread {
	@Override
	public void run() {
		for (int i = 1; i < 4; i++) {
			System.out.println("正在洗第" + i + "个菜");
			try {
				this.sleep(300);
				System.out.println("洗完第" + i + "个菜");
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
}

测试类Test

package Homework;

public class Test1 {
	public static void main(String[] args) throws InterruptedException {

		Xicai xc = new Xicai();
		Qiecai qc = new Qiecai();
		Chaocai cc = new Chaocai();
		Shangcai sc = new Shangcai();
		
		xc.start();
		qc.start();
		cc.start();
		
		xc.join();
		qc.join();
		cc.join();
		sc.start();
	}
}
