Java Anonymous Function Purpose Explained

Anonymous function, also known as lambda expression in Java, mainly serves to simplify code writing and reduce redundant code. By using anonymous functions, functions can be defined directly where a function needs to be passed as a parameter, without the need to define a separate function. This not only enhances the readability and maintainability of the code, but also makes it more convenient to implement the principles of functional programming. Anonymous functions are commonly used in implementing functional interfaces, such as in collection operations, multi-threading processing, event handling, and so on.
