Stream: - It is an API introduced in Java 8 used to process a collection of objects. It primarily has two types of operations: -

• Intermediate Operations
• Terminal Operations

It is a combination of one or more intermediate operations followed by a terminal operation. Each intermediate operation is lazily executed and returns a stream as a result, hence, various intermediate operations can be pipelined. Terminal operations mark the end of the stream and return the result.

Some common intermediate and terminal operations are as follows: -

1. map: - It is an intermediate operation used to return a stream consisting of the results of applying the given function to the elements of this stream.

JAVA
1<R> Stream<R> map(Function<? super T, ? extends R> mapper)

2. filter: - This intermediate operation is used to select elements as per the Predicate passed as an argument.

JAVA
1Stream<T> filter(Predicate<? super T> predicate)

3. sorted: - It is an interm...
