A final class in Java is a concept of object-oriented programming where a class is declared using the "final" keyword. This type of class cannot be extended or inherited by other classes, making it inflexible. In this article, we will discuss the basics of the final class in Java, includ...
Today, it’s almost impossible to browse the internet or run applications if your computer doesn’t support Java. Developed by Sun Microsystems back in 1995, Java has been around for more than a decade now. It is one of the most popular programming languages in the world due to its power...
Abstract classes in Java play a key role in object-oriented programming (OOP). They serve as blueprints for other classes, defining the structure their subclasses must follow. It enhances code organization, promotes code reusability, and enforces consistency. In this blog, we will explore the con...
It cannot access non-static data member or methods. So if you are planning on calling a non-static data member you must first make that data member static by using the static keyword like we did in the final part ofhow to use classes in java chapter. If you make a class method as s...

In the OOPs concepts guide, we learned that object oriented programming is all about objects. The eight primitive data types byte, short, int, long, float, double, char and boolean are not objects, Wrapper classes are used for converting primitive data t
In Java and other object oriented languages, a class is a blueprint or a template from which objects are created. Classes are defined by users as a template for defining data and behavior of the objects that are created from that class. Classes are the b

In this article, we’ll explore the different ways of finding an object’s class in Java. 2. Using the getClass() Method The first method that we’ll check is the getClass() method. First, let’s take a look at our code. We’ll write a User class: public class User { // impl...
