Java线程范围内的共享数据

同样的代码，一个线程身上一分数据

import java.util.HashMap;
import java.util.Map;
import java.util.Random;

public class ThreadScopeShareData {

	private static int data = 0;
	private static Map<Thread, Integer> threadData = new HashMap<Thread,Integer>();
	
	public static void main(String[] args) {
		
		for(int i = 0;i<2;i++){
			new Thread(new Runnable() {
				public void run() {
					int data = new Random().nextInt();
					System.out.println(Thread.currentThread().getName()+
							" has put data: "+data);
					threadData.put(Thread.currentThread(),data);
					new A().get();
					new B().get();
				}
			}).start();
		}
	}
	static class A{
		public void get(){
			int data = threadData.get(Thread.currentThread());
			System.out.println("A from "+Thread.currentThread().getName()+
					" get data: "+data);
		}
	
	}
	static class B{
		public void get(){
			int data = threadData.get(Thread.currentThread());
			System.out.println("B from "+Thread.currentThread().getName()+
					" get data: "+data);
		}
	}

}
