Objects may have different state and behavior. Example - In world different animals have different names like Lion, … The concept of using classes and objects is to encapsulate state and behavior into a single programming unit. This concept is called encapsulation. Java objects are similar to real-world objects. For example, we can create a car object in Java, which will have properties like current speed and color; and behavior like: accelerate and park

    Software Objects • A Java class is a “blue print” for creating objects of that type. • We then can create multiple objects from that class and “fill in” the properties with values specific to each object, and ask the object to perform their behaviors. • Every object belongs to one class and is an instance of the class. Class in Java. A class in Java or any other Object-oriented Language is a blueprint for objects to follow a specific schema defined in the class. Classes define the behavior for objects of its type.
