Stream VS ParallelStream

凡事无绝对，存在即合理
直接上代码示例：

public class MainTest {

    public static void main(String[] args) {
        List integerList = Lists.newArrayList(1,2,3,4,5,6);

        integerList.stream().forEach(data->System.out.println(Thread.currentThread().getName() +":"+ data));
        
        System.out.println("----------------我是分割线--------------------");

        integerList.parallelStream().forEach(data->System.out.println(Thread.currentThread().getName() +":"+ data));
        
    }

}
