1，线程状态转换

无限期等待：

限期等待：

线程生命流程：

2，实现方式

代码实现样例【三种方式】：

package com.cnblogs.mufasa.demo2;

import java.util.concurrent.Callable;

public class test1_Runnable implements Runnable{
    @Override
    public void run() {
        for(int i=0;i<50;i++){
            System.out.println("当前线程："+i);
        }
    }
}

class test2_Callable implements Callable<String> {
    private int num;
    public test2_Callable(){}
    public test2_Callable(int num){
        this.num=num;
    }
    @Override
    public String call() throws Exception {
        for(int i=0;i<50;i++){
            System.out.println(this.num+"线程:"+i);
        }
        return num+"线程已完成";
    }
}

class test3_Thread extends Thread {
    private int num;
    public test3_Thread(){}
    public test3_Thread(int num){
        this.num=num;
    }
    @Override
    public void run() {
        for(int i=0;i<50;i++){
            System.out.println(this.num+"线程:"+i);
        }
    }
}

package com.cnblogs.mufasa.demo2;

import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;

public class Client {
    public static void main(String[] args) throws ExecutionException, InterruptedException {
        //实现 Runnable 接口
//        test1_Runnable instance=new test1_Runnable();
//        Thread thread=new Thread(instance);
//        Thread thread1=new Thread(instance);
//        thread.start();
//        thread1.start();

        //实现 Callable 接口
//        test2_Callable instance=new test2_Callable(1);
//        FutureTask<String> ft=new FutureTask<>(instance);
//        Thread thread = new Thread(ft);
//        test2_Callable instance1=new test2_Callable(2);
//        FutureTask<String> ft2=new FutureTask<>(instance1);
//        Thread thread1 = new Thread(ft2);
//
//        thread.start();
//        thread1.start();
//        System.out.println(ft.get());
//        System.out.println(ft2.get());

        //继承 Thread 类
        test3_Thread thread1=new test3_Thread(1);
        test3_Thread thread2=new test3_Thread(2);
        thread1.start();
        thread2.start();

    }
}
