一篇文章带你入门java多线程

package com.zhouzy.base.t10;
public class RunnableTest implements Runnable{
	@Override
	public void run() {
		System.out.println("实现Runnable接口创建的线程，线程名:"+Thread.currentThread().getName());
	}
}

package com.zhouzy.base.t10;
public class ThreadTest extends Thread{
	@Override
	public void run() {
		System.out.println("继承Thread创建的线程，线程名:"+Thread.currentThread().getName());
	}
}

package com.zhouzy.base.t10;
import java.util.concurrent.Callable;
public class CallableTest implements Callable<String>{
	@Override
	public String call() throws Exception {
		System.out.println("实现Callable接口创建的线程，线程名:"+Thread.currentThread().getName());
		return "这是Callable接口返回的";
	}
}

    @Test
	public void threadTest(){
		try {
			//Runnable接口测试
			RunnableTest runnable = new RunnableTest();
			Thread runThread = new Thread(runnable);
			runThread.setName("Runnable线程");
			runThread.start();
			//继承Thread测试
			ThreadTest t = new ThreadTest();
			t.setName("Thread线程");
			t.start();
			CallableTest call = new CallableTest();
			FutureTask<String> ft = new FutureTask<>(call); 
			Thread ct = new Thread(ft);
			ct.setName("Callable线程");
			ct.start();
			System.out.println("callable线程返回值:"+ft.get());
		}catch (Exception e) {
			e.printStackTrace();
		}
