You will need various information about the dogs like different breeds of the dogs, the age, size, etc. Moreover, the million dollar question is, how you design such software? Here is the solution-.

Some of the differences you might have listed out maybe breed, age, size, color, etc. If you think for a minute, these differences are also some common characteristics shared by these dogs. These characteristics breed, age, size, color can form a data members for your object. Next, list out the common behaviors of these dogs like sleep, sit, eat, etc. So these will be the actions of our software objects.

Now, for different values of data members breed size, age, and color in Java class, you will get different dog objects. In the below program, we have declared a class called Dog.

Thus, this is the main difference between Class and Object. Also, an important difference between Class and Object is that Class is a logical entity while Object is a physical entity. A class does not get any memory when it is created whereas objects get memory when they are created.
