"A class hierarchy or inheritance tree''' in CS is a 분류,classification of object types, // link object_type ? or not?
denoting objects as the instantiations of classes (클래스,class is like a 청사진,blueprint, the 객체,object is what is built from that blueprint)
inter-relating the various classes by relationships such as

• "inherits",
  
• "extends",
  
• "is an abstraction of",
  
• "an interface definition".
  

In object-oriented programming, // OO OOP
a class is a template
that defines the state and behavior common to objects of a certain kind. // OOP에서 클래스란 특정한 종류,kind의 객체들에 공통인 상태,state와 행동,behavior을 정의,definition한 틀,template(템플릿,template)이다.
A class can be defined in terms of other classes. // (그 외에도) 클래스 정의는 다른 클래스에 대해 할 수 있다. i.e. 다른 클래스를 가지고 그 관계를 서술하는 방법으로 할 수 있다.
The concept of class hierarchy in computer science is very similar to taxonomy =,taxonomy . taxonomy taxonomy taxonomy taxonomy taxonomy { Taxonomy_(biology) = https://en.wikipedia.org/wiki/Taxonomy_(biology) }, the classifications of 종,species. =,species . species { species species species 설명 species }

The relationships are specified in the science of object-oriented design(object-oriented_design) and object interface standards defined by popular use, language_designers (Java, C++, Smalltalk, Visual_Prolog) and standards committees for software_design like the Object_Management_Group =,Object_Management_Group . Object_Management_Group | =,OMG .{ Object Management Group Object_Management_Group Object_Management_Group Object_Management_Group Object Management Group Object Management Group "Object Management Group"}.

The class hierarchy can be as deep as needed. The 인스턴스변수,instance_variables들 and 메소드,methods들 are inherited down^{상속,inheritance} through the 레벨,levels and can be redefined according to the requirement in a subclass. In general, the further down in the hierarchy a class appears, the more specialized its behavior.
When a message is sent to an object, // 메시지,message(of OO)가 객체,object로 전달되면,
it is passed up the inheritance tree // 트리,tree의 위로 올라간다 - 루트,root쪽으로...
starting from the class of the receiving object
until a definition is found for the method. 메소드,method 정의,definition
This process is called upcasting." // upcasting =,upcasting =,upcasting . upcasting { 업캐스팅 upcasting 업캐스팅 업캐스팅 upcasting .... opp. 다운캐스팅 - cmp.
