continuing until all elements are processed or an exception occurs. Introduced in Java 8, this method offers developers a modern, concise alternative to traditional looping constructs, simplifying the process of iterating over collections.
peek map 和 peek 都是 Stream 提供的流处理方法。 首先看 peek 的使用源码注释: This method exists mainly to support debugging, where you want to see the elements as they flow past a certain point in a pipeline: 翻译: 这个方法主要用于支持 debug 调试,当你想看处于某个特定点的流元素时 如: @...

Performs the given action for each entry in this map until all entries have been processed or the action throws an exception.
java foreach 语法是在jdk1.5时加入的新特性,主要是当作for语法的一个增强,那么它的底层到底是怎么实现的呢?因为面试时被问到,所以在这边做一个记录。 首先来看看foreach能够使用的类型是什么: 编译器报错原因写的很清楚了,要求:数组或java.lang.Iterable。
static void foreachMethod(){ for (Suit suit2 : suit) { for (Rank rank2 : rank) { System.out.println(suit2+"+"+rank2); } } } 1. 2. 3. 4. 5. 6. 7. 从上面的例子可以看出,使用for-each循环以后,程序清晰了很多,并且不容易出错。
