How to learn OOPS concepts? Join Java Training in Pune! OOPS Join the advanced Java Training in Pune and get to know OOPS concepts in detail. Objects are considered an important aspect of the Object Oriented Programming concept. The objects can be created as per the user’s choice which will, in turn, be used for accessing the objects. In modern programming concepts like Java, OOPS is widely used. Core OOPS concepts are 1) Class Similar attributes together constitute a class. It is regarded as a logical component and not the physical entity. For instance, if you have a class named Employee details then it will contain details like employee name, id, profile, address, number etc. The methods in this class would be like HR, Sales, Manager, etc. 2) Object An instance of a class is termed as an object and there are lots of instances of a class in the program. Both the data and the function is present in the object which uses the data. 3) Inheritance When an object acquires the properties and behaviors of the parent object then it is called as Inheritance. It is very useful in organizing and structuring any software. 4) Polymorphism The ability of a variable, object or function to create various forms of itself is referred to as a polymorphism. For instance, the word train would provide a different meaning while boarding the train when compared to undergoing training. Polymorphism follows the same concept.
