What are the features of a lambda expression?

Question

Accepted Answer

Lambda expressions are anonymous functions that can be passed as arguments or returned from methods.

Lambda expressions are concise and can be used to represent a single method interface.
They do not have a name, return type, or access modifier.
They can have zero or more parameters and a body that contains the code to be executed.
Lambda expressions can be used in functional interfaces to provide implementation for abstract methods.
Example: (x, y) -> x + y is a lambda expression that takes two parameters and returns their sum.

Accepted Answer

Lambda expressions are a concise way to represent anonymous functions and are a key part of functional programming in Java.
1) Works with Functional Interfaces: Lambdas can only be used with functional interfaces, which are interfaces with exactly one abstract method (e.g., Runnable, Callable, Comparator).

2) Concise Syntax: Lambdas remove the need for anonymous class boilerplate, making the code cleaner and easier to read.
3) Type Inference: The compiler can infer the types of parameters, so you don’t need to explicitly declare them.
4) Improves Readability: Lambdas make the code shorter and more intuitive, especially for operations like filtering, sorting, or iteration.
5) Supports Inline Implementation: Allows the inline implementation of functional logic without requiring separate class definitions.
