Question

Need help in this question. Must be in java.

the class diagram with four classes student, graduate, undergraduate, and exchange is given. Write the classes as described in the class diagram. The fields and methods for each class is given below.

Fields: major (String)
Student:

gpa (double)

creditHours (int)

Methods:

getGpa: returns gpa

getYear: returns “freshman”, “sophomore”, “junior” or “senior” as determined by earned credit hours:

Freshman: Less than 32 credit hours
Sophomore: At least 32 credit hours but less than 64 credit hours
Junior: At least credit hours 64 but less than 96 credit hours
Senior: At least 96 credit hours

Graduate:

Fields: degree (String) (“Masters” or “PhD”)

concentration (String)

years (int) (stores no. of years spent in grad school)

Methods:

getYear: returns years (this is an integer, not like the student…)

getConcentration: returns concentration (ex: Data Science, NeuroScience, Bioinformatics, Cybersecurity, etc.)

Undergraduate:

Fields: honors (Boolean)

Methods:

isHonors: returns honors (TRUE or FALSE)

Exchange:

Fields: country (String)

year(string) (start date of the exchange program, stores Fall, Spring or Summer followed by the year e.g., Fall 2020)

Methods:

getYear: returns year

getCountry: returns country
