带返回值的多线程实现

package cn.thread;import java.util.concurrent.*;/** * @author Duoduo * @version 1.0 * @date 2017/4/19 15:49 */public class Test2 {    public static void main(String[] args) throws ExecutionException, InterruptedException {        ExecutorService executorService = Executors.newFixedThreadPool(2);        Race tortoise = new Race("Tortoise", 1000L);        Race rabbit = new Race("Rabbit", 300L);        Future<Integer> tortoiseSubmit = executorService.submit(tortoise);        Future<Integer> rabbitSubmit = executorService.submit(rabbit);        Thread.sleep(5000);        tortoise.setFlag(false);        rabbit.setFlag(false);        int torStep = tortoiseSubmit.get();        int rabStep = rabbitSubmit.get();        System.out.println("Tortoise run " + torStep + torStep + " step  and Rabbit run " + rabStep + " step");        executorService.shutdownNow();    }}class Race implements Callable<Integer> {    private String name;    private Long time;    private boolean flag = true;    private int step = 0;    public Race(String name, Long time) {        this.name = name;        this.time = time;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Long getTime() {        return time;    }    public void setTime(Long time) {        this.time = time;    }    public boolean isFlag() {        return flag;    }    public void setFlag(boolean flag) {        this.flag = flag;    }    public int getStep() {        return step;    }    public void setStep(int step) {        this.step = step;    }    @Override    public Integer call() throws Exception {        while (flag) {            Thread.sleep(time);            step++;            System.out.println("name " + name + " step " + step);        }        return step;    }}

运行结果
name Rabbit step 1
name Rabbit step 2
name Rabbit step 3
name Tortoise step 1
name Rabbit step 4
name Rabbit step 5
name Rabbit step 6
name Tortoise step 2
name Rabbit step 7
name Rabbit step 8
name Rabbit step 9
name Tortoise step 3
name Rabbit step 10
name Rabbit step 11
name Rabbit step 12
name Rabbit step 13
name Tortoise step 4
name Rabbit step 14
name Rabbit step 15
name Rabbit step 16
name Tortoise step 5
name Rabbit step 17
Tortoise run 55 step and Rabbit run 17 step
