Java8新特性之线程安全的时间日期API尝试

嗯，这篇博客只有代码，重要的是线程安全

package cn.ycl.test;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
//这是Java8以后才有的线程安全的时间日期API
public class test01 {
	public static void main(String[] args) throws InterruptedException, ExecutionException {
		
		//自定义格式，就像jdk7中的simpleDateFormat（）方法一样
		DateTimeFormatter dtf=DateTimeFormatter.ofPattern("yyyyMMdd");
		//创建线程
		Callable<LocalDate> callable=new Callable<LocalDate>() {
			@Override
			public LocalDate call() throws Exception {
				return LocalDate.parse("20161218",dtf);
			}};
			//用于存储执行线程的返回值
			List<Future<LocalDate>> list = new ArrayList<>();
			
			//创建线程池，这是有界线程池
		ExecutorService pool = Executors.newFixedThreadPool(10);
		
		
		//执行线程并将结果加入list
		for (int i = 0; i < 20; i++) {
			list.add(pool.submit(callable));
		}
		for(Future<LocalDate> future :list) {
			System.out.println(future.get());
		}
		pool.shutdown();
	}
}
