JUC-Callable

一、是什么
是获得多线程的方式之一
还有实现Runnabe、继承Thread类
二、怎么用
package com.cb.demo.example;

import org.omg.PortableServer.THREAD_POLICY_ID;

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

class MyThread implements Runnable{

@Override
public void run() {

}
}

class MyThread2 implements Callable{

@Override
public Integer call() throws Except

JUC-Callable最先出现在Python成神之路。
