The following are the some of the differences between object and class:

Object Class
An object in java programming language is considered as an instance of class. A class in java programming language is considered as a template from which objects are created.
An object is referred as a real world entity that is tangible. A class in java programming language is considered as a group of similar objects.
An object is considered as a physical entity. A class in java programming language is considered as a logical entity.
We create objects in java by using the new keyword. In Java programming language a class is created or declared by using the class keyword.
An object in java can be created a number of times in a program. Class is created or declared only once in java programming language.
When an object is created in java programming language memory is allocated automatically. No memory is allocated when a class is created in Java programming language.
An object in java programming language can be created by many different ways for example by using the new keyword, or through the newInstance () method, etc. In java programming language there is only one way through which a class can be created or declared that is by using the class keyword.
