Functional Programming with Lambdas and Streams

Write lambda expressions to provide implementations for functional interfaces.

Use common built-in functional interfaces from java.util.function (Predicate, Function, Consumer, Supplier).

Create a stream from a collection, array, or range of values.

Chain intermediate stream operations like filter(), map(), and sorted() to build a data processing pipeline.

Execute a stream pipeline using terminal operations like collect(), forEach(), and reduce().
