Question

(JAVA) Write an abstract superclass encapsulating a college
   applicant: A college applicant has two attributes:
   the applicant’s name and the college the applicant
   is applying to. This class has two non-abstract
   subclasses: one encapsulating an applicant for
   undergraduate school, and the other encapsulating
   an applicant for graduate school. An applicant for
   undergraduate school has two attributes: a SAT score
   and a GPA. An applicant for graduate school has one
   additional attribute: the college of origin.
   It also has a method that returns “from insideâ€
   if the college of origin is the same as the college
   applied to; otherwise, it returns “from outsideâ€.
   You also need to include a class to test two classes. (JAVA)

Answer 1

Solution:

Please find the code below for the above problem:

// super class with 2 attributes
abstract class Applicant{
   public String applicantsname;
   public String appliedCollegename;

   // class for undergraduate applicant
   class underGrad extends Applicant{
       double SATscore;
       double gpa;
   }
  
   // class for graduation applicant
   class Grad extends Applicant{
       double SATscore;
       double gpa;
       String collegeOfOrigin;
       String getCollegeName()
       {
           if(appliedCollegename == collegeOfOrigin)
               return "from inside";
           else
               return "from outside";
       }
       String fromInsideOrOutside = getCollegeName();
   }
  
   // class for testing
   public class Test {

       public void main(String[] args) {
           // TODO Auto-generated method stub

           Grad grad = new Grad();
           grad.applicantsname = "name of the applicant";
           grad.appliedCollegename = "name of the college applied for";
           grad.gpa = 9.4;
           grad.SATscore = 85;
           grad.collegeOfOrigin = "name of the college of origin";
       }
   }
}

Please find the attached screenshot for the same:

We had nothing much to do for the class UnderGrad, so I have just given values and tested the Class Grad.

You can easily do for UnderGrad by creating an instance for it and then give the values using the instance.

Thanks!
