Question

Write a simple Java program that does the following:
1) Declare a constant of type String to hold the words "Oakland University".
2) Declare variables of the type stated, and Prompt the user to enter in the following information and store in the variables
a. Their current GPA on a 4.0 scale, into a variable of type double
b. The number of credits they have so far into a variable of type int
c. The amount of tuition they paid so far into a variable of type int
d. Their last name, into a String variable
e. Their first initial, into a char variable
3) Create a variable of type char. Determine and assign a letter grade to it using the following rules and if else statement. (Note: this is not our class grading scheme.)
a. gpa < 1 F
b. 1 <= gpa < 2.5 D
c. 2.5 <= gpa < 3 C
d. 3 <= gpa <= 3.5 B
e. 3.5 < gpa <= 4 A

4) Create a variable of type double. Cast the either of the variables tuition or credits to
double to calculate the tuition dollars per credit hour and assign it to the new variable. .
5) Print out to the system console a single String using escape characters that outputs
multiple lines with the following information, formatted the same as this example. In
other words, the first column should indicate what is being output, and the second column
shows the value. Use variable names in your output String, not literals. You can use tab
escape characters to set up the second column.
a. your first initial and last name, with a period and space following your first initial
(from problem 2)
b. your university (from problem 1)
c. your Letter GPA grade (from problem 3)
d. Your tuition cost per credit hour (from problem 4)

Answer 1

import java.util.Scanner;

public class StudentCred {
   public static void main(String[] args) {
       final String unName = "Oakland University";
       Scanner sc = new Scanner(System.in);
       //reading gpa
       System.out.println("Enter gpa:");
       double gpa = sc.nextDouble();
       //reading credits
       System.out.println("Enter number of credits: ");
       int credits = sc.nextInt();
       //reading fee
       System.out.println("Enter total tution fee: ");
       int tutionFee = sc.nextInt();
       //reading name
       System.out.println("Enter lastName: ");
       String lastName = sc.nextLine();
       lastName = sc.nextLine();
       //reading initial
       System.out.println("Enter initial: ");
       char initial = sc.next().charAt(0);
       char grade;
       //finding grade
       if (gpa < 2.5)
           grade = 'D';
       else if (gpa >= 2.5 && gpa < 3)
           grade = 'C';
       else if (gpa >= 3 && gpa <= 3.5)
           grade = 'B';
       else
           grade = 'A';
       //finding fee
       double dollorsPerCredit = tutionFee / (double) credits;
       System.out.println("Name : " + lastName + "." + initial);
       System.out.println("University Name :" + unName);
       System.out.println("GPA grade: " + grade);
       System.out.println("Tution cost per credit hour: " + dollorsPerCredit);

   }
}
