       Scanner sc = new Scanner(System.in);
       double min = 1000, max = -1;
       double grade;

           System.out.println("Enter as many student grades as you like. Enter a character to stop.");

       while (true) {
           try {
               grade = sc.nextDouble();
           } catch (Exception e) {
               //breaking if user enters
               break;
           }
           //checking if grade is less than min
           // make grade as min
           if (grade < min)
               min = grade;
           //checking if grade is greater than max
           // make grade as max
           if (grade > max)
               max = grade;
       }
       //printing the results
       System.out.println("The highest grade is: " + max);
       System.out.println("The lowest grade is: " + min);
