안녕하세요, HELLO 파이썬에서 클래스(class)는 데이터와 이를 처리하는 메서드(함수)로 구성됩니다. 이번에는 python의 클래스(class)에 대해서 자세히 살펴보고자 합니다 STEP 1. '클래스(class, init...
initialize는 '기본값 설정하기'라는 뜻에 가깝다(대개 __init__을 '초기화' 라고 설명하는데 한국 IT어 용례상 '기본값 설정하기'로 이해하는 편이 낫다). 이제부터 시작되는 예시 코드 및...
Sometimes it is useful to wrap a value in a class to create a more domain-specific type. However, it introduces runtime overhead due to additional heap allocations. Moreover, if the wrapped type is primitive, the performance hit is significant, because primitive types are usually heavily optimized by the runtime, while their wrappers don't get any special treatment. To solve such issues, Kotlin introduces a special kind of class called an inline class. Inline classes are a subset of value-based ...
Constructors ; Primary constructor parameters can be used in the initializer blocks. They can also be used in property initializers declared in the class body: ; Kotlin has a concise syntax for declaring properties and initializing them from the primary constructor: ; Such declarations can also include default values of the class properties: ; You can use a trailing comma when you declare class properties:

⟨ Extend a class ; Mixins are a way of defining code that can be reused in multiple class hierarchies. They are intended to provide member implementations en masse. ; To use a mixin, use the with keyword followed by one or more mixin names. The following example shows two classes that use (or, are subclasses of) mixins: ; To define a mixin, use the mixin declaration. In the rare case where you need to define both a mixin and a class, you can use the mixin class declaration.
