Java Stream of()用法及代码示例 Stream of(T t) 流(T t)返回包含单个元素的顺序Stream。 用法: static Streamof(T t) 参数:此方法接受强制参数t,该参数是Stream中的单个元素。 返回值:Stream of(T t)返回包含单个指定元素的顺序Stream。 例: // Java code for Streamof(T t)// to get a sequential...
首先调用Stream.of方法根据一个Integer对象数组构建了流,函数内部是通过调用Arrays.stream方法返回流,对应的Spliterator实现是ArraySpliterator,然后调用filter方法过滤,我们分析下这个阶段对应的源码 @OverridepublicfinalStream<P_OUT> filter(Predicate<?superP_OUT>predicate) { ...
