What distinguishes a collection and stream

Question

Accepted Answer

A collection is a group of objects, while a stream is a sequence of objects that can be processed in a pipeline.

A collection is a data structure that stores multiple elements, such as an array or a list.
A stream is a sequence of elements that can be processed in a pipeline of operations.
Collections are typically mutable, meaning elements can be added, removed, or modified.
Streams are typically immutable, meaning they do not change the original sequence of elements.
Collections provide random access to elements, allowing direct retrieval by index.
Streams are lazily evaluated, meaning they only process elements as needed.
Collections are suitable for small to medium-sized data sets.
Streams are suitable for large or infinite data sets.
Collections can be iterated using loops or iterators.
Streams support functional-style operations like map, filter, and reduce.
Collections are often used when the entire data set needs to be stored and accessed frequently.
Streams are often used when data processing involves transformations, filtering, or aggregations.
