UML Diagram - Answers - Can be used to summarize the properties of a class
Instance Variable - Answers - can be accessed outside of the class using the "."
operator
Method - Answers - defines an action that an object can perform, it can also be called
outside of the class by using the "." operator
Access Modifiers - Answers - Used to specify how a class, method, or instance variable
can be accessed
Public Method or instance variable - Answers - a method that is accessible to another
method of any other class
Private Method or instance variable - Answers - a method that is only accessible to
methods in the same class
Null Constant - Answers - Can be used as a placeholder for a variable that does not
refer to an actual object
Void Method - Answers - Does NOT return a value
Method Header Contains: - Answers - Access Modifier: Public
Return Type: void
Name of method: writeOutput
Parameter list: ()
Method Body - Answers - Sequence of statements that is executed when the method is
called, surrounded by {}
Method can be defined to return a value - Answers - True
When method is called: - Answers - Return value should be stored in a variable
Keyword "this" - Answers - refers to the object that is performing the action specified by
the method
, Local Variable - Answers - A variable that is declared inside of a method body and cant

call
Encapsulation - Answers - means details of a class are hidden if they are not necessary
