Question

Please write a java program that has the following methods in it: (preferably in order)  

1. a method to read in the name of a University and pass it back
2. a method to read in the number of students enrolled and pass it back
3. a method to calculate the tuition as 20000 times the number of students and pass it back
4. a method print the name of the University, the number of students enrolled, and the total tuition

Design Notes:

• The method described in Item #1 above will read in a string and pass it back to the main program. Nothing is passed to the method, but the University name is passed back
  
• The method described in Item #2 above will read in an integer for the number of students enrolled and pass it back to the main program. Nothing is passed to the method, but the University name is passed back to the main program
  
• The method described in Item #3 above will receive the number of students. It will then do the calculation for the tuition and pass back that value, which is a double value to the main program
  
• The method described in Item #4 above will receive all data for printing and pass nothing back to the main program
  

Please copy the java code along with a screen print (snippet) of the final output. I would like both to review the work that I already have done. Thanks in advance!

Java class :

StudentsClass.java :

//import package
import java.util.*;

//Java class
public class StudentsClass {
   // main() method
   public static void main(String[] args) {
       // call method to get university name
       String uniName = universityName();
       // call method to get number of students
       int numStudents = numberOfStudents();
       // call method to calculate tuition fee
       double tuition = calculateTuitionFee(numStudents);
       // call method to display details
       printDetails(uniName, numStudents, tuition);

   }

   // a method to read in the name of a University and pass it back
   public static String universityName() {
       // Object of Scanner class
       Scanner sc = new Scanner(System.in);
       // asking user university name
       System.out.print("Enter University Name : ");
       // reading name
       return sc.nextLine();
   }

   // a method to read in the number of students enrolled and pass it back
   public static int numberOfStudents() {
       // Object of Scanner class
       Scanner sc = new Scanner(System.in);
       // asking user number of students
       System.out.print("Enter number of students : ");
       // reading number of students
       return sc.nextInt();
   }

   // a method to calculate the tuition as 20000 times the number of students and
   // pass it back
   public static double calculateTuitionFee(int numStudents) {
       // calculate and return tuition fee
       return numStudents * 20000;
   }

   // a method print the name of the University, the number of students enrolled,
   // and the total tuition
   public static void printDetails(String uniname, int numStudents, double tuition) {
       // print details
       System.out.println("University Name : " + uniname);// print university name
       System.out.println("Number of Students : " + numStudents);// print number of Students
       System.out.println("Tuition Fee: " + tuition);// print tuition fee
   }
}
