Compact, easy-to-read lambda expressions for methods that already have a name
When a lambda expression does nothing but call an existing method. In those cases, it's often clearer to refer to the existing method by name. Method references enable you to do this

Kinds of Java Method Reference -
1.Reference to a static method - ContainingClass::staticMethodName
2. Reference to an instance method of a particular object - containingObject::instanceMethodName
3. Reference to an instance method of any arbitrary object of a particular type - ContainingType::methodName
4. Reference to a constructor - ClassName::new
