State and behavior. ANSWER -Real world objects share which two characteristics?
In object oriented programming how is state represented?. ANSWER -Member variables
Methods. ANSWER -in object oriented programming how is behavior represented?
Serve as the blueprint of how objects will be created. ANSWER -What is the purpose of a
class in object oriented programming?
True. ANSWER -Based on best practices and how the Java API Library is implemented a
class should start with a capital letter (i.e. Dog versus dog).
False. ANSWER -When defining a class, member variables are included within the class's
open/close curly braces (i.e. {}) and methods are defined outside of the open/close curly
braces.
