Kas saak selgitada, mis on anonüümne funktsioon programmeerimises ja kuidas seda kasutatakse?

An anonymous function is a function without a name, which is usually created and used "on the spot", without the need to declare it separately. In Android (Java or Kotlin), anonymous functions are often used for event handling, callbacks, or in functional programming.

Example in Kotlin:

val sum = { a: Int, b: Int -> a + b }
println(sum(3, 4)) // Will print 7

Here, { a: Int, b: Int -> a + b } is an anonymous function that adds two numbers. Such functions are convenient to pass as parameters to other functions or for short data processing.
