Functional programming with Java collections

Streams and lambdas provide powerful ways to work with Java collections, making functional programming easier and more efficient. Java 8 introduced these features, allowing developers to use functional operations like sort, forEach, map, filter, and reduce on collections without modifying the original data. These operations enhance code readability and maintainability by enabling a more declarative syntax and composable pipelines. Additionally, converting different types of collections into streams unlocks the potential for these functional techniques across various data structures.
