Java中多线程类ExecutorService的使用

package com.threadPool;

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

public class ThreadPoolTest {
  
  public void mainMethod(){
    //获取线程池类
    ExecutorService threadPool = Executors.newFixedThreadPool(5);
    String str = "hello";
    //执行方法
    AutoTest autoTest = new AutoTest(str);
    threadPool.execute(autoTest);   
  } 
  
  public void syso(String str){
    System.out.println(str);
  } 
    
  class AutoTest implements Runnable{
    private String str;
    public AutoTest(String s){
      str = s;
    } 
    @Override
    public void run() {
      syso(str);
    }
  }

}
