Create a class named Grades, which has four fields, one for the name of the student, and three other fields for grades in test1, test2 and test3. The class should contain two constructors: a no-argument constructor that sets all fields to zero, and a constructor that sets all fields to a given value. The class should have the appropriate methods to “set” and “get” the values of all fields. The class should also have a method to calculate the average of the three tests. To test the class, you should create a class demo that instantiates one object of the Grades class and asks the user enter the student name and the grades for the three tests. The program should set the fields to the values entered by the user using the “set” methods, and output to the console the student name, the grades for test1, test2 and test3 as well as their average using “get” methods.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Create a class named Grades, which has four fields, one for the name of the student, and three other fields for grades in test1, test2 and test3. The class should contain two constructors: a no-argument constructor that sets all fields to zero, and a constructor that sets all fields to a given value. The class should have the appropriate methods to “set” and “get” the values of all fields. The class should also have a method to calculate the average of the three tests.

The program should set the fields to the values entered by the user using the “set” methods, and output to the console the student name, the grades for test1, test2 and test3 as well as their average using “get” methods.
