Lambda expressions
Anonymous functions defined inline using concise syntax enabling functional programming. Lambda expressions reduce boilerplate for simple functions.
Real World
Netflix uses lambda expressions extensively in its Java codebase to filter and sort its catalogue of 17,000+ titles — e.g. filtering all films rated 4+ stars in a single line rather than writing a separate named function.
Exam Focus
When asked to 'write' a lambda, show equivalent named function too — markers award marks for demonstrating understanding, not just syntax.
