一、多线程简单用法

1、Thread

Thread thread1= new Thread() {
   @Override
   public void run() {
      System.out.println("===Threading");
   }
};
thread1.start();

Runnable （相当于Thread.run()那样并不能当多线程使用，详情分析：二、多线程之Thread中run 和start 区别 ）

new Runnable(){
   @Override
   public void run(){
      System.out.println("===Runnableing");
   }
}.run();

2、Thread和Runnable

new Thread(new Runnable() {
      @Override
      public void run() {
         System.out.println("===Thread and Runnableing");
      }
   }).start();
