What is polymorphism Mcq
The word polymorphism refers to many-forms, so if a single entity takes more than one form, it is known as polymorphism. Explanation: It is actually the capacity for a message or piece of data to be processed in more than one way.
What is polymorphism Java
Simply put, polymorphism in Java allows us to perform the same action in a variety of ways. Polymorphism in Java refers to the ability of a class to provide different implementations of a method, depending on the type of object that is passed to the method.
What is polymorphism and types of polymorphism
There are two types of polymorphism in Java: compile time polymorphism and run time polymorphism, which are also known as static polymorphisms and dynamic polymorphisms. Polymorphism is the ability to process objects differently depending on their class and data types.
Which is runtime polymorphism in Java OOPS Mcq
Compile-time polymorphism, which is met by operator and function overloading, is also known as early or static binding. Runtime polymorphism, which is met by function overriding, is also known as late or dynamic binding.
What is truncation in Java Mcq
Truncation in Java programming refers to removing some digits from a float or double-type number or some characters from a strings right side. We can also remove the entire decimal portion to convert the number to an integer.
What is polymorphic operation
A single message will result in a different response depending on the class of the object to which it is sent in the case of polymorphic operations, where the same operation may be implemented differently in each subclass.
How is polymorphism achieved
Runtime polymorphism: This kind of polymorphism is accomplished through Function Overriding, which takes place when a derived class has a definition for one of the base classs member functions, which is referred to as an overridden base function.5 days ago
Which of the following is a type of polymorphism in Java select one
We can perform polymorphism in Java by method overloading and method overriding. If you overload a static method in Java, it is an example of compile time polymorphism. There are two types of polymorphism: compile-time polymorphism and runtime polymorphism.
What is encapsulation in OOP Mcq
It is a method of combining member functions that work on data members and the data members themselves into a single unit.
What is Java encapsulation
Encapsulation, which is the grouping of fields and methods inside a single class to prevent outer classes from accessing and altering those fields and methods and to help achieve data hiding, is one of the main characteristics of object-oriented programming.
What is subclass in Java
Classes in the Java programming language can be derived from other classes, inheriting their fields and methods in the process.
What is abstract method in Java
It is only possible to use an abstract method in an abstract class, and it lacks a body; the body is provided by the subclass (from which it is inherited), which is a restricted class that cannot be used to create objects.
What is encapsulation explain
Information hiding, also known as encapsulation, is the practice of concealing an objects internal representation or state from the outside world. Encapsulation is defined as the idea of grouping data and methods that operate on that data within a single unit, similar to a class in Java.
Which inheritance is not supported in Java Mcq
Option (a) is the appropriate response to the question “Which inheritance in Java Programming is not supported,” as Java does not support Multiple inheritances using classes but does support user interfaces. Mar 23, 2021
What is the advantage of runtime polymorphism in Java Mcq
The ability of the class to offer the specification of its own to another inherited method is the main benefit of runtime polymorphism. This transfer of implementation of one method to another method is possible without changing or modifying the codes of the parent class object.
What is the association in Java
In Java, an association is a connection or relation between two distinct classes that is established through their objects. It can be one-to-one, one-to-many, many-to-one, or many-to-many, and it describes how the objects are aware of and using the functionality of one another.
What is false constructor
Explanation: The constructor cannot have a return type because it must create and return new objects, which would result in a compilation error.
How is inheritance defined in Java
In Java, classes may inherit or acquire the properties and methods of other classes; a class that is descended from another class is referred to as a subclass, and the class from which a subclass is descended is referred to as a superclass.Jun 3, 2022
