Stream API in Java 8: A Comprehensive Guide
Introduction: Stream API is one of the most significant features introduced in Java 8. It provides a powerful and efficient way to process data by allowing developers to perform a sequence of operations on a collection of objects. In this comprehensive guide, we will dive into the Stream API in Java 8 and explore how it can be used to process data effectively. Stream API is used to process collections of objects. A Stream API is a sequence of objects that support various methods which can be pipelined to produce the desired result. Features of Java Streams API: A Stream is not a data structure instead it takes input from the collections, Arrays, or I/O channels. Streams don't change the original data structure, they only provide the result as per the pipelined methods. Each intermediate operation are lazily executed and returned a stream as a result, hence various intermediate operation can be pipelined. Terminal operation mark the end of the stream and returns the result. 1. Wha...
