 What is stream API, why is it needed?

Ans:-  stream is an interface from java.util.stream package which supports stream of objects,which means continuous flow of objects.

Stream<T> will perform the following operations:-

a. Intermediate operations

b.Terminal operations

=> The stream API is needed for several reasons:-

1.Functional programming Paradigm:-

The Stream API supports functional programming paradigm, allowing developers to express operations on data in a concise and expressive manner.

2.Parallelism:- The stream API supports parallel processing, making it easier to take advantage of multi-core processors .Parallel stream can be created to process elements concurrently.

3.Code Readability:- Using the Stream API often leads to more readable and maintainable code. 

4.Efficient Operations:- Stream operations, such as map, filter, and reduce, are designed to be efficient.
