    An instance of a class is called object. The object has state and behavior.

    Whenever the JVM reads the “new()” keyword then it will create an instance of that class.

    Example:

    1 public class Addition{
    2 public static void main(String[] args){
    3 Addion add = new Addition();//Object creation
    4 }
    5 }

    An object has a state and behavior. The state of an object is stored in fields (variables), while methods (functions) display the object’s behavior. Objects are created from templates known as classes.

    Object

    In object-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 generic class of object and even more generic classes are defined so that objects can share models and reuse the class definitions in their code. Each object is an instance of a particular class or subclass with the class’s own methods or procedures and data variables. An object is what actually runs in the computer.

    An object may refer to any of the following:

    1. In general, an object refers to any item, either in the physical or virtual world. For example, a computer is considered an object in the physical world. In the virtual world, a documentfilefolder, and picture are all considered objects.

    2. In computer graphics, an object refers to an item within a graphic, such as a graphic circle or a square.

    3. When dealing with computer programming, see the object-oriented programming definition.

    4. When referring to HTML, the <object> tag is used to designate an object embedded into a web page.

    s the name object-oriented implies, objects are key to understanding object-oriented technology. You can look around you now and see many examples of real-world objects: your dog, your desk, your television set, your bicycle.

    These real-world objects share two characteristics: they all have state and they all have behavior. For example, dogs have state (name, color, breed, hungry) and dogs have behavior (barking, fetching, and slobbering on your newly cleaned slacks). Bicycles have state (current gear, current pedal cadence, two wheels, number of gears) and behavior (braking, accelerating, slowing down, changing gears).

    Software objects are modeled after real-world objects in that they, too, have state and behavior. A software object maintains its state in variables and implements its behavior with methods.
