java之ThreadLocal简单使用总结（2）

package com.sangfor.threadlocal;
public class TestThreadLocal {
  public static final ThreadLocal<Integer> sThreadLocal = new ThreadLocal<Integer>(){
     @Override
       protected Integer initialValue() {
       return 0;
       }
  };
  public static void main(String[] args) {
    for (int i = 0; i < 10; i++) {
      new MyThread(i).start();
    }
  }
  static class MyThread extends Thread {
    public int index;
    public MyThread(int index) {
      this.index = index;
    } 
    @Override
    public void run() {
      System.out.println("线程" + index + "的初始value:" + sThreadLocal.get());
            for (int i = 0; i < 10; i++) {
              sThreadLocal.set(sThreadLocal.get() + i);
              }
          System.out.println("线程" + index + "的累加value:" + sThreadLocal.get());
        }
  }
}
