Java / Collections

What is the difference between Streams and Collections in Java 8?

Collection is used for storing data in different data structures while Stream API is used for computation of data on a large set of Objects.

Collection API we can store a finite number of elements in a data structure. With Stream API, we can handle streams of data that can contain infinite number of elements.

Eager vs. Lazy: Collection API constructs objects in an eager manner. Stream API creates objects in a lazy manner.

Multiple consumption: Most of the Collection APIs support iteration and consumption of elements multiple times. With Stream API we can consume or iterate elements only once.
