Program 3 - Students and grades Submit your program files in a folder called RU07 in your directory on neelix.

Description: Write a Student class and a driver to compute student grades.

Write a Student class which keeps track of a student and grades for that student. Instance data for the student class should include:

Strings for the first and last name of the student
integers for 3 quiz grades. Quiz grades are on a 10 point scale.
integers for the midterm and final exam grades, on a 100 point scale.
doubles for the quiz average and the semester average

The Student class will also have one static variable, count, which will count the number of students which were instantiated.

The Student class should have methods to do the following:

a constructor, which will initialize all the instance data. Assume the student's name is known at the time of instantiation, but the student's grades will be entered later.
a toString, which will format a grade report for the Student, including all the instance data as well as letter grades.
an enterGrades which gets all the 3 quiz grades, the midterm and final exam grades from the driver. This method can also calculate the grade averages. The semester average is calcuated thus: quiz ave is worth 25% of the sem grade, the midterm is worth 35%, and the final exam is worth 40% of the semester average. This method could also return the semester average.
consider creating private toLetter methods, which receive a grade and return a char, the letter for the number grade passed to it. Assume a straight 10 point grading scale: 90-100 A, 80-89 B, 70-79 C, 60-69 D, below 60, F. (No plus or minus grades.)
a static getCount method, which returns the value of the static var count.

Write a driver called program3.java which lets the user enter information for students until they are done. The driver should ask for a student's first name, last name, quiz grades 1,2, and 3, midterm grade, and final exam grade. The driver will then output a nicely formatted grade report for the student. The driver will then ask the user if they'd like to enter information for another student (y or n).

When the user is done entering student info, and types n to quit, the program will output the number of students entered and the average of semester averages for all students entered.

TURNING IN YOUR PROGRAM: You will turn in two files. You'll have the driver program, named program3.java, and the Student class, named Student.java. Submit both files to neelix in a folder called RU07 in your folder.
