Streams-and-Lambda-Expressions

Streams and lambda expressions are powerful features in modern programming, particularly in Java. Streams represent a sequence of elements that can be processed in a functional style, allowing for efficient data manipulation through operations like filtering, mapping, and sorting. They enable developers to handle large datasets seamlessly, processing data as it arrives rather than in bulk.

Lambda expressions, on the other hand, provide a concise way to express instances of single-method interfaces. They simplify code by allowing functions to be treated as first-class citizens, making it easier to write and maintain code. Together, streams and lambda expressions enhance productivity and promote a functional programming approach.
