Java 8 Method Reference Example

Date: 2018-01-19

Java 8's method references provide a concise way to refer to existing methods within lambda expressions, improving code readability. They act as shorthand for lambda expressions that simply call another method, using the double-colon operator (::). Method references, like lambdas, require a functional interface (an interface with a single abstract method). Four types of method references exist: to static methods, instance methods of a particular object, instance methods of an arbitrary object, and constructors. This feature reduces code volume and enhances clarity in Java 8 and above.
