Need help with making program: The java program must contain a main $()$ method. Standard programming practice locates the

main $()$ method at the end of the program. The program class must be the same name as the java

file name.

The first class is the Student class. It has three instance variables which include the student

name, credit hours earned and quality points. At a minimum, it should have following methods:

$$ A constructor that allows the student$$s name, credit hours and quality points to be

initialized.

$$ A method named gpa that returns the student$$s grade point average, which is

computed as the quotient of the quality points and credit hours.

$$ A method eligibleForHonorSociety that returns whether a student$$s gpa exceeds the

threshold for honor society membership, which applies to all students.

$$ A toString method that returns a string containing the student name and grade point

average

$$ A class $($static$)$ method setGpaThreshold that sets the minimum gpa threshold for

honor society membership.

The Student class has two subclasses.

The first is Undergraduate. It has an additional instance variable that specifies the student$$s

year: either a freshman, sophomore, junior or senior. At a minimum, it should have following

methods:

$$ A constructor that allows the student$$s name, credit hours, quality points and year to

be initialized.

$$ An overridden method eligibleForHonorSociety that applies the requirement that the

student be either a junior or senior in addition to the requirement that applies to all

students to be eligible for honor society membership.

$$ An overridden toString method that returns a string containing the student$$s name,

grade point average, and year.

The second subclass is Graduate. It has an additional instance variable that reflects whether

the student is pursuing a master$$s degree or doctorate at a minimum, it should have following

methods:

$$ A constructor that allows the student$$s name, credit hours, quality points and degree

sought to be initialized.

$$ An overridden method eligibleForHonorSociety that applies the requirement that the

student be seeking a master$$s degree in addition to the requirement that applies to all

students to be eligible for honor society membership.

$$ An overridden toString method that returns a string containing the student$$s name,

grade point average, and degree sought.

Finally, there should be a fourth class DataControl.. It should read in student information from a

text file named students.txt$.$ If the file does not exist, an error message is displayed, and the

program should terminate. Each line of the text file will represent the information for one

student
