Problem Statement

In object-oriented programming a method is a function associated with a particular class or object. In most forms of object oriented implementations methods can be static, associated with the class itself; or instance, associated with an instance of a class. Show how to call a static or class method, and an instance method of a class.

Let's start with the solution:

(Long/toHexString 15) ; use forward slash for static methods
(System/currentTimeMillis)

(.equals 1 2)    ; use dot operator to call instance methods
(. 1 (equals 2)) ; alternative style
