Lab2 프로젝트 디렉토리 안에 모든 파일(src/*.java & bin/*.class)와 보고서 (2~3장)를 넣고 Lab2_학번_이름.zip 압축한 후 e-learning(http://lms.dankook.ac.kr/index.jsp)으로 제출 ()
Lab2 – Basics (method, for, foreach, if, switch, do/while, while, array 활용)
수업블로그에 2.Basic 안에 TemperatureConverter 클래스 참고하여, 본인이 원하는 Converter 클래스를 추가작성한다 (예시: degree <-> radian 변환, kilometer <-> mile 변환, kilogram <-> pound 변환, 등등).

Object − objects have states and behaviors.
Class – defines the grouping of data and code, the “type” of an object
Instance – a specific allocation of a class
Message – sent to objects to make them act
Method – a “function” that an object knows how to perform
Local Variables − variables defined inside methods, constructors or blocks
Instance Variables – variables within a class but outside any method (a specific piece of data belonging to an object)
Class Variables − variables declared within a class, outside any method, with the static keyword
Encapsulation – keep implementation private and seperate from interface
Polymorphism – different objects, same interface
Inheritance – hierarchical organization, share code, customize or extend behaviors
