Method References in Java

Method references in Java provide a concise way to refer to methods without invoking them. They are a part of the lambda expressions feature introduced in Java 8, designed to simplify the syntax and improve code readability. Method references are particularly useful in functional programming, where functions are treated as first-class citizens.

Summary

• Method references provide a concise way to refer to methods without invoking them.


• There are four types of method references: static, instance, constructor, and arbitrary object method references.


• Method references are widely used in the Streams API, functional interfaces, and the Collections Framework.
