控制多线程执行顺序

Posted 2021-01-24 cuihongyu

虽然项目用不上，先备份吧，控制多线程执行顺序有两种方法

1.通过join方法保证多线程的顺序性的特性

join：让主线程等待子线程结束后才能继续执行

public  static void main(String[] args) throws InterrupterException
{
    thread1.start();
    thread1.join();
    thread2.start();
    thread2.join();
    thread3.star();
}

2.
ExcutorService executor = Excutors.newSingleTheadExcutor():FIFO

static ExcutorService excutorService = Excutors.newSingleTheadExcutor();
public  static void main(String[] args) throws InterrupterException
{
    excutorService.submit(thread1);
    excutorService.submit(thread2);
    excutorService.submit(thread3);
}
