In Java, method overriding occurs when a subclass (child class) has the same method as the parent class. Overriding is a feature that allows a subclass or child class to implement a method that is already provided by one of its super-classes or parent classes. When a subclass’s method has the same name, parameters, signature, […]

Method Overloading in Java: Method Overloading occurs when a class has multiple methods with the same name but different parameters. Compile-time (or static) polymorphism is linked to overloading. The readability of the program is improved by method overloading. We don’t have to develop new names for functions that do the same thing. Overloading the method […]

Association: Association is a relation between two separate classes which establishes through their Objects. One-to-one, one-to-many, many-to-one, and many-to-many associations are all possible. An Object communicates with another object to use its functionality and services in Object-Oriented programming. Composition and Aggregation are the two forms of association. Composition: The strongest type of association is composition. It represents part-of relationship. If […]

In Java, inheritance is a mechanism by which one object inherits all of its parent’s properties and behaviors. It is an essential component of OOPs (Object-Oriented programming systems). You can use the parent class’s methods and fields when you inherit from an existing class. You can also add new methods and fields to your current […]

Copy constructor: A copy constructor is a type of constructor in Java that creates an object by copying another object from the same Java class. It returns a copy of a class object that already exists. If we want to, we can use the copy constructor: Make […]

A method is a block of code, a group of statements, or a set of code that performs a specific task or operation. These are also known as functions in other programming languages. The method describes the behavior of an object. It increases code reusability. It also provides an easy modification of the code. Method Declaration: […]

What is OOPs? Object-Oriented Programming is a methodology or paradigm for designing a program using classes and objects. Many concepts, such as inheritance, data binding, polymorphism, and others, are available in Object-Oriented Programming. It takes a practical approach to solve a problem. As a result, object-oriented programming is a better and easier way to write programs […]
