What is Method Reference in Java 8? | Java 8 New Features
👉 Welcome to CODiiN, your trusted software training institute in Kochi, Kerala! In this section of our Java 8 New Features Course, we will explore Method References, a powerful feature that simplifies the use of functional interfaces in Java.
📖 What is a Method Reference?
A Method Reference is a shorthand notation of a lambda expression to call a method. It provides a way to refer to a method without executing it. This feature enhances code readability and reduces boilerplate code when using functional interfaces. Method references can be used with various built-in functional interfaces, such as Runnable, Consumer, Supplier, Function, etc.
🌟 Types of Method References
There are four main types of method references in Java:
Reference to a Static Method:
Syntax: ClassName::staticMethodName
Reference to an Instance Method of a Particular Object:
Syntax: instance::instanceMethodName
Reference to an Instance Method of an Arbitrary Object of a Particular Type:
Syntax: ClassName::instanceMethodName
Reference to a Constructor:
Syntax: ClassName::new
🌟 Benefits of Using Method References
Improved Readability: Method references provide a more concise and clearer syntax compared to lambda expressions.
Less Boilerplate Code: They reduce repetitive code, making it easier to understand and maintain.
