Understand:method is called with ().To be more abstract, the method is a variable name, and "()" is a simple representation of the calling method (also for the compiler to recognize), and the calling method is the result of the operation.Eg:a = 1; A is a variable name, and "=" is a simple expression of the assignment (but we have been in touch with the language for too long and the subconscious has assumed that = is the assignment.) But in fact, "=" into the @, replaced by "assignment", and what
