Difference between Class and object in Java

"Student" is a class. And "Jenna" is an object of the class "Student". And "John" is another object of the class "Student".
A Class is template for an object, a user-defined datatype that contains the variables and methods in it.

           A class defines the abstract characteristics of a thing (object), including its characteristics (its attributes, fields or properties) and the thing's behaviors (the things it can do, or methods, operations or features).
That is, Class is a blue print used to create objects. In other words, each object is an instance of a class.
One class can have multiple number of instances. (There can be Number of instances of the class "Student", like "Jenna", "John" etc).

A class is a blue print, in which its mentioning what all variables it (it means an object of that class) will have, what all methods it will have.
