Java并发之Callable和Runnable

Java并发中,提供的Callable和Runnale最大的区别即为:

    Callable接口可以返回值,而Runnable不能返回值;

package com.leasehouse;import java.util.concurrent.*;public class TestCallable {    public static void main(String[] args) {       ExecutorService executorService = Executors.newFixedThreadPool(10);       try {          Future<User1> future = executorService.submit(new taskCallable());          User1 ff = future.get();          System.out.println("ff = " + ff.getName());       } catch (InterruptedException e) {          e.printStackTrace();       } catch (ExecutionException e) {          e.printStackTrace();       } finally {          executorService.shutdown();       }    }}class taskCallable implements Callable<User1> {  public User1 call() throws Exception {        String cc = "fyc";        System.out.println("cc =" + cc);        User1 user1 = new User1();        user1.setName(cc);        Thread.sleep(3000);        return user1;   }}class User1 {  private String name;  public String getName() {    return name;  }  public void setName(String name) {    this.name = name;  }}
