How do I define a method which takes a lambda as a parameter in Java 8?

In Java 8, methods can be created as Lambda expressions and can be passed by reference (with a little work under the hood). There are plenty of examples online with lambdas being created and used with methods, but no examples of how to make a method taking a lambda as a parameter. What is the syntax for that?

MyClass.method((a, b) -> a+b);


class MyClass{
  //How do I define this method?
  static int method(Lambda l){
    return l(5, 10);
  }
}
