In OOP, abstraction means hiding the complex implementation details of a program, exposing only the API required to use the implementation. In Java, we achieve abstraction by using interfaces and abstract classes. We can read more about abstraction in our abstract class and interface articles. 5....
Java - What is OOP? OOP stands forObject-Oriented Programming. Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods. ...
In the program given below, we are creating an object of Student class using theclone()method. This method can be used if and only if at least one object of the class is already created. Also makes sure thatCloneableclass is implemented in a class. While calling theclone()method we requ...

Java provides two ways to implement polymorphism. Static Polymorphism (compile time polymorphism/ Method overloading):The ability to execute different method implementations by altering the argument used with the method name is known as method overloading. In below program, we have three print ...
Inobject-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. In between, each object is made into a genericclassof object, and even more generic classes are defined...
