NOTES:
In Java 8, streams are a powerful new tool for working with collections of data. They allow you to perform operations on the data in a sequential or parallel fashion, and they can be chained together to form complex pipelines.
One of the key concepts of streams is the distinction between intermediate and terminal operations. Intermediate operations are those that return a new stream as a result. This means that they can be chained together with other intermediate operations to form a pipeline. Terminal operations, on the other hand, do not return a new stream. They perform an operation on the current stream and produce a result, such as a count, a sum, or a collection of elements.
Here are some examples of intermediate operations:
🔹filter(): This operation returns a new stream containing only the elements that match a given predicate.
🔹map(): This operation returns a new stream containing the results of applying a given function to each element of the original stream.
🔹sorted(): This operation returns a new stream containing the elements of the original stream sorted according to a given comparator.
Here are some examples of terminal operations:
🔹forEach(): This operation performs an action on each element of the stream.
🔹count(): This operation returns the number of elements in the stream.
🔹max(): This operation returns the maximum element in the stream.
