Java 9 Stream takeWhile with examples
Java 8 introduced the Stream API which allows processing and applying some operations to the elements in a Collection. Java 9 has made some improvements to the Stream API . One such improvement is the takeWhile method. In this article, I will be covering the Java 9 Stream takeWhile method in detail. I will also be writing some Java 9 takeWhile examples. The takeWhile method operates on a Stream. It accepts a Predicate instance and applies the Predicate to all the elements in the input stream and produces an output stream. It behaves differently depending on whether the input Stream is ordered or unordered. takeWhile on Ordered Stream As per the API documentation, when the takeWhile is applied on an ordered Stream, it returns, a stream consisting of the longest prefix of elements taken from this stream that match the given predicate if the stream is ordered. So basically, the takeWhile method applies the Predicate on each element in the input Stream until the condition in the Predica...
