jdk1.8新特性：stream流 报错：stream has already been operated upon or closed

这个异常表示stream流已经被使用或者关闭。jdk8种的stream流是不可复用的，使用一次后就会被关闭，二次使用必须重新创建stream流。例如：publicstaticvoidmain(String[]args){Listlist=newArrayList();list.add("huawei");list.add("apple");list.add("oppo");list.add("vi

消除多次调用rand()函数产生相同的随机数

这是因为srand((unsigned)time(NULL));这条语句虽然避免了在for(i=0;i>&w){inti,j;for(i=0;i>&w){inti,j;if(operated){srand

【Java没基础】关于stream has already been operated upon or closed问题

在学习Java8函数式编程的相关知识的时候，做了一个小练习题：很简单啊，于是我键盘一挥，使用并行流写了如下代码publicstaticintparallelSumOfSquares(IntStreamrange){returnrange.parallel()//这里直接将流转化为并行流.map(x->x*x).sum();}然后呢，为了测试效果，我还准备将两个方法的结果做一下对比（这里为了效果明显
