For example: As in case of Shape class which we need for inheritance and polymorphism but want only to instantiate objects of its subclasses, not Shape itself. The following is java abstract class example. //Show how to create abstract class and method abstract class Shape { abstract void...
Java is a platform-independent, object-oriented programming language. Java uses an OOP programming concept like Abstraction, Inheritance, Polymorphism, Encapsulation. Java takes anything as an object. The objects have classes, methods, and attributes.Answer and Explanation: The reference variable is used...
which is currently allowed in method names by the Java VM, but not allowed by the compiler. (Some byte code obfuscators use this trick to prevent decompilation.) This would avoid any accidental conflicts with old code. For example,
The language treated everything as an object and follows the object-oriented rules like: Encapsulation, Abstraction, Data hiding, Polymorphism, and inheritance.Answer and Explanation: Parameter: The parameters are variable which is declared initiated when the method is created In simple we can say th...
Today a follow-up to my 2010 article about the meaning of the is operator. Presented as a dialog, as is my wont! I've noticed that the is operator is inconsistent in C#. Check this out: string s = null; // Clearly null is a legal value of type string boo

What is a function in computer programming? Explain the concept of encapsulation. Provide an example to illustrate your points and also provide the pseudocode. Define polymorphism and how is used in OOP. What is the function of communication networks? How are local declarations stored in computer ...
In a structured programming language, the problem is divided into functions. Each function performs a specific task. This may lead to unnecessary repetition of code. Functions are made for code re-usability and for saving time and space. There are two types of functions in all programming ...
