Question 1 a) Polymorphism polymorphism enables us to compile schedules that march butts that share the same superkinsperson in a descent power structure as if they are all objects of the superclass. A variable with a aband unmatchabled name may be allowed to have opposite compliances and the course of instruction thunder mug escort which form of the variable to lend oneself at the time of execution. For example, a variable named USERID may be capable of universe each an whole number (whole number) or a string of characters (perhaps because the computer programmer wants to allow a drug user to assume a user ID as either an employee number - an integer - or with a name - a string of characters). By giving the program a way to distinguish which form is existence handled in each case, either kind jackpot be acknowledge and handled. b) Inheritance Object-oriented programming allows classes to inherit commonly used narrate and behavior from other classes. In this example, pedal now becomes the superclass of MountainBike, RoadBike, and TandemBike. In the Java programming language, each class is allowed to have one direct superclass, and each superclass has the potential for an unmeasured number of subclasses:. varying Variables are simply names used to link to just about post in memory a location that holds a value with which we are working.
It may help to think of variables as a placeholder Identifierj r names given to program elements such as variables , arrays & functions. Basically identifers r the sequences of alphabets or digits. an identifier is a combinat ion of alphanumeric characters, the first be! ing a letter of the alphabet or an underline, and the remaining being both letter of the alphabet, any numeric digit, or the underline  kind A class is a mechanism for creating user-defined selective information types. a class is composed of a cross out of data members and a set of operations that can be performed on the class. In C++, a class type can be stated with the keywords union, struct, or class. A union object can...If you want to regain a full essay, order it on our website: OrderCustomPaper.com
