Thread类、Runnable接口、Lambda表达式

继承Thread类

package com.mashibing.juc.c_000_threadbasic;
import java.util.concurrent.*;
public class T02_HowToCreateThread {
    static class MyThread extends Thread {
        @Override
        public void run() {
            System.out.println("Hello MyThread!");
        }
    }
    //启动线程的5种方式
    public static void main(String[] args) throws Exception {
        new MyThread().start();
    }
}

实现Runnable接口

相比继承Thread类，这种实现Runnable接口的方式更合适 因为一个类实现Runnable接口后还可以从其他类去继承 但一个类继承了Thread类之后不能再从其他类继承

package com.mashibing.juc.c_000_threadbasic;
import java.util.concurrent.*;
public class T02_HowToCreateThread {
    static class MyRun implements Runnable {
        @Override
        public void run() {
            System.out.println("Hello MyRun!");
        }
    }
    //启动线程的5种方式
    public static void main(String[] args) throws Exception {
        new Thread(new MyRun()).start();       
    }
}

使用Lambda表达式

package com.mashibing.juc.c_000_threadbasic;
import java.util.concurrent.*;
public class T02_HowToCreateThread {
    //启动线程的5种方式
    public static void main(String[] args) throws Exception {
        new Thread(() -> {
            System.out.println("Hello Lambda!");
        }).start();
    }
}
