我是靠谱客的博主瘦瘦巨人，最近开发中收集的这篇文章主要介绍Callable与Future,FutureTask，觉得挺不错的，现在分享给大家，希望可以做个参考。

主类：
callable+future

public class TestFuture {
	public static void main(String[] args) {
        ExecutorService threadPool = Executors.newCachedThreadPool();
        Future<Boolean> uFuture = threadPool.submit(new UpdateCallable(6000));
        Future<Boolean> IFuture = threadPool.submit(new InsertCallable(12000));
        try {
        	threadPool.shutdown();//直到线程执行完毕
            boolean flag = true;
            while(flag){
            	if(uFuture.get()&&IFuture.get()){
            		flag = false;
            		System.out.println("is over!");
            	}
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }
}

callable+futureTask

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


public class testFutureTask {
	public static void main(String[] args) {
	  ExecutorService threadPool = Executors.newCachedThreadPool();
	  UpdateCallable utask = new UpdateCallable(6000);
	  InsertCallable itask = new InsertCallable(12000);
      FutureTask<Boolean> UfutureTask = new FutureTask<Boolean>(utask);
      FutureTask<Boolean> IfutureTask = new FutureTask<Boolean>(itask);
      threadPool.submit(UfutureTask);
      threadPool.submit(IfutureTask);
      try {
      	threadPool.shutdown();//直到线程执行完毕
          boolean flag = true;
          while(flag){
          	if(UfutureTask.get()&&IfutureTask.get()){
          		flag = false;
          		System.out.println("is over!");
          	}
          }
      } catch (InterruptedException e) {
          e.printStackTrace();
      } catch (ExecutionException e) {
          e.printStackTrace();
      }
  } 
}

Callable：

import java.util.concurrent.Callable;

public class InsertCallable implements Callable<Boolean> {
	private Integer time = 3000;

	public InsertCallable(Integer time) {
		super();
		this.time = time;
	}

	public Boolean call() throws Exception {
		System.out.println("InsertCallable sleep time:" + time);
		Thread.sleep(time);
		System.out.println("InsertCallable up");
		return true;
	}
}
import java.util.concurrent.Callable;

public class UpdateCallable implements Callable<Boolean> {
	private Integer time = 3000;

	public UpdateCallable(Integer time) {
		super();
		this.time = time;
	}

	public Boolean call() throws Exception {
		System.out.println("UpdateCallable sleep time:" + time);
		Thread.sleep(time);
		System.out.println("UpdateCallable up");
		return true;
	}
}
