A Guide to Intermediate and Terminal Operations with Java Streams
A Java Stream is a sequence of elements that can be processed in a functional style using operations such as filter, map, and reduce. A stream is different from a collection in that it does not store elements itself, but rather provides a way to process elements from a source, such as a collection or an I/O channel.
What are the benefits of using streams in Java?
Streams provide a concise and expressive way to process collections of data. They support functional programming paradigms such as immutability and lazy evaluation, and can make code more readable and maintainable. Streams also provide built-in support for parallel processing which can improve performance for certain types of operations.
You can create a stream from a collection in Java by calling the stream() method on the collection. For example;
List<Payment> payments = new ArrayList<>();
Stream<Payment> paymentStream = payments.stream();
