Learn to use Stream forEach(Consumer action) method to traverse all the elements of stream and performs an action for each element of this stream. Java StreamforEach()method is used toiterate over all the elements of the givenStreamand to perform anConsumeractionon each element of the Stream...
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: @...

foreach是一种用于遍历集合或数组的循环结构,但它不适用于类型为"java.lang.String"的对象。 "java.lang.String"是Java中表示字符串的类,它是不可变的,即一旦创建就不能被修改。由于字符串是一个字符序列,而不是一个集合或数组,因此无法使用foreach循环来遍历它。 然而,我们可以使用其他方式来处理字符串。例如,...
