Difference Between Class And Object In Java
Differentiation between class and object
In Java, there are many differences between an object and class. Let’s see,
| Object | Class |
| Object is an instance of a class in Java. | Class is a blueprint or a template in which objects are created. |
| Object is a real world entity such as bike, car, mobile, pencil, table, chair etc. | Class is a collection of similar type of objects. |
| Object is a physical entity in Java. | Class is a logical entity in Java. |
| Object is created through new keyword mainly e.g. Car c1=new Car(); |
Class is created, using class keyword e.g. class Car{} |
| We can create object many times as per our requirement. | Class is created only once. |
| Object allocates the memory at the time of creation. | Class doesn't allocate the memory at the time of creation. |
| We can create object through many ways in Java such as new keyword, newInstance() method, clone() method, factory method and deserialization. | Class is only one way to define in Java, using class keyword. |
Summary
Thus, we learnt that object is an instance of a class in Java and class is a blueprint or a template in which objects are created.
