How are data transforms generally used? - Answer- Generally used to map data from a source to a target as well as performing transformations on that data required to achieve the intended mapped results. What is the data transform pyDefault? - Answer- Created for new cases, allows you to set properties as the case is created If properties are set in both the superclass and subclass, what happens? - Answer- The data transform in the subclass overwrites anything already sey by the data transf...

A call to a final method can only be resolved at run time - False A final method in a superclass cannot be overridden in a subclass - True A method declared as private in the superclass can be overridden in the subclass - False A static method in a superclass can be overridden in the subclass - False ENUM type is value type - False - Enum type is reference type A subclass can inherit (extends) from a final class. - F

Subclasses correct answers - inherits all properties, behaviors, and fields of its superclass - inherits private fields and methods in its superclasses, but it cannot directly access them - can have more methods than its superclass - classes can only extend one superclass - subclass is a type of a superclass object - constructor automatically calls its superclass's default constructor (error if it doesn't have one) - can explicitly invoke its superclass constructor using super - executi...

The process of inheritance should establish a(n) ___________________ relationship. a) is-a b) has-a c) static d) not-a e) none of the above - correct answer (A.) (is-a) Inheritance should establish an is-a relationship. Therefore any objects that are of a type lower in the inheritance hierarchy are also of a type higher in the inheritance hierarchy. The original class that is used to derive a new class using inheritance is called ____________________ . a) a superclass b) a par...

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...

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...
