1.MyThread2类

public class MyThread2<V> implements Callable<V>{
	private V v;
	
	public MyThread2(V v){
		
		this.v = v;
		
	}

	@Override
	public V call() throws Exception {
		
		return v;
	}
	
	
}

2.测试类

public class MyThread2Test {
	
	public static void main(String[] args) throws InterruptedException, ExecutionException {
		
		ExecutorService executorService = Executors.newFixedThreadPool(5);
		
		List<Future<Integer>> resultList = new ArrayList<Future<Integer>>();
		for (int i = 0; i < 5; i++) {
			
			Callable<Integer> c = new MyThread2<Integer>(i);
			
			Future<Integer> result = executorService.submit(c);
			
			resultList.add(result);
					
		}
		
		
		for (int i = 0,size = resultList.size(); i < size; i++) {
			
			Integer f = resultList.get(i).get();
			
			System.out.println(f);
			
		}
		
	}
}
