Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
Java is an object-oriented programming language. Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.
An object in Java is a basic unit of Object-Oriented Programming and represents real-life entities. Objects are the instances of a class that are created to use the attributes and methods of a class. A typical Java program creates many objects, which as you know, interact by invoking methods.
An object stores its state in fields (variables in some programming languages) and exposes its behavior through methods (functions in some programming languages). Methods operate on an object's internal state and serve as the primary mechanism for object-to-object communication.
Objects and classes are the core concept of object-oriented programming. In this tutorial, you will learn about the objects and classes in Java with the help of examples.

1. Overview. In this article, we’ll look into Object-Oriented Programming (OOP) concepts in Java. We’ll discuss classes, objects, abstraction, encapsulation, inheritance, and polymorphism. 2. Classes. Classes are the starting point of all objects, and we may consider them as the template for creating objects.
