Serializing Objects correct answers An object can be represented as a sequence of bytes that includes the objects data as well as information about the objects type and the types of data stored. Super() correct answers A method call in a sub class constructor invokes the superclass constructor Overloading correct answers Having multiple methods with same name but different signatures in a class Overriding correct answers Overrides the functionality of an existing method but not if it is...

Abstraction provides correct answers high level model of activity Procedural abstraction correct answers Specifies actions performed hides algorithms Data abstraction correct answers Specifies data objects for the problem Hides implementations Encapsulation correct answers hides implementation details while providing interface (methods) for data access allows us to use code without knowing its implementation makes debugging and code modification simple Interface correct answers S...

What is a subtype discriminator? - ANSWER -basically you're estimating the trade off between having inconsistencies & redundancies for ease of searching the database by using a type -An attribute of the supertype whose values determine the target subtype(s) true or false: an associative entity belongs to a one-to-many relationship - ANSWER false—only many-to-many if you have a unary relationship with your database, what will the conversion look like? example: ingredients( INum, INa...

Overriding - correct answer When you create a method that already exists in a parent class, the new class overrides this class Overloading - correct answer Having methods with the same name but different parameters so Java knows which one to use. @Override - correct answer A hint to Java that you are overriding the superclass Java extends - correct answer extends a class to another class Java implements - correct answer implements an interface Program development - correct answer ...

To be useful in science, a hypothesis must be .... - Answer-Testable What is meant by a 'controlled' experiment? - Answer-An independent variable is the only factor allowed to be adjusted, with the dependent variable as the factor that the independent variable affects. What is the difference between the control group and the experimental group? - Answer-Experimental group receives the variable being tested/ one variable at a time.

a detailed answer with context to help students focus on what is important. Answers are designed to be con cise and understandable, which means that different answers require different presentations. Comparison questions compute the key differ ences between two concepts, building on the learn ing principle of conceptual contrast (Ausbel 1965). The result is displayed in a table, keeping the infor mation well organized. Context is provided with short definitions and superclass infor...
