Kas saaksite selgitada lambda-väljendite tööpõhimõtet programmeerimises?

Lambda expressions are anonymous functions that can be passed as objects and used for concise functional code writing. In Java, they allow writing compact code to implement interfaces with a single method (functional interfaces).

Principle of operation:

• A lambda expression describes behavior (a function) without the need to create a separate class.
• It can accept parameters and return results.
• It is used, for example, for processing collections, events, or streams.

Example:

List<String> names = Arrays.asList("Anna", "Bob", "Charlie");
names.forEach(name -> System.out.println(name));

Here, name -> System.out.println(name) is a lambda expression that prints each element of the list to the screen.
