CS 1713 -- Simple Student class

Work with classes: The `Student` class

Here is a program that solves one of the practice problems for the final exam. (Answers to question in boldface.)


// Student.java: a simple class holding information about a student
public class Student {
   private String name; // In the form "LastName, FirstName"
   private double GPA; // grade point average
   private int collegeClass; // 1 = FR, 2 = SO, 3 = JR, 4 = SR, 5 = GR

   public Student(String n, double gpa, int c) { // constructor
      name = n; GPA = gpa; collegeClass = c;
   }

   public double getGPA() { // return the GPA
      return GPA;
   }

   public String toString() {
      return "Name: " + name + ", GPA: " + GPA +
             ", Class Code: " + collegeClass;
   }
}


// Students.java: test the Student class
public class Students {
   public static void main (String[] args) {
      Student jBlow =    new Student("Blow, Joe", 3.4, 2);
      Student bBonkers = new Student("Bonkers, Bruce", 2.9, 3);
      Student nNutcase = new Student("Nutcase, Nancy", 3.7, 2);
      System.out.println(jBlow + "\n" + bBonkers + "\n" + nNutcase);
      System.out.println("GPA of JoeBlow: " + jBlow.getGPA());
   }
}

The output:


Name: Blow, Joe, GPA: 3.4, Class Code: 2
Name: Bonkers, Bruce, GPA: 2.9, Class Code: 3
Name: Nutcase, Nancy, GPA: 3.7, Class Code: 2
GPA of JoeBlow: 3.4
