Erp Solutions Oodles12 Sep, 2023Web Development

Java provides a new fresh package in Java 8 called java.util.stream. This package i.e. java.util.stream, consists of interfaces, classes and enum to allows functional-style operations on the element. You can use stream by importing java.util.stream package into a project. Stream provides following features: Stream doesn't store element. It simply transfers elements from a source such as a an array, data structure or an I/O channel, through a channel of computational operations. Stream is functional in nature. Operations performed on a stream doesn't modify it's source. For example, filtering a Stream attained from a collection produces a new Stream without the filtered element, rather than removing elements from the source collection. Stream is lazy and evaluates code only when needed.
