Question

Write a program using the switch statement name GradeReport that reads a grade as an integer value from the user and prints the comments accordingly. Prompt the user to enter their grade User must be prompt to enter a numeric grade (0 to 100) if the input isn't an integer between 0 and 100, prompt the user to re-enter Use a while loop for the re-enter of grade then if condition is not met or grade is not between 0 and 100 then prompt the user on the screen as follows ("Error: You must enter an integer between 0 and 100");" Also incorporate a while loop to keep track of tries. Create a variable name "tries" that will keep track of tries no more than 3 therefore if the input isn't an integer between 0 and 100, prompt the user to re-enter

Explanation / Answer

GradeReport.java

public class GradeReport {

  
   public static void main(String[] args) {
       java.util.Scanner in = new java.util.Scanner(System.in);
       int grade = 0;
       int tries = 0;
       int TOTAL_CHANCES = 3;
       int category = 0;
       while(tries < TOTAL_CHANCES){
           System.out.println("Please enter the grade between 0 and 100");
           grade = in.nextInt();
           if(grade >= 0 && grade <= 100){
               category = grade / 10;
               switch(category){
               case 10: System.out.println("Perfect score job well"); break;
               case 9: System.out.println("well above average. Excellent"); break;
               case 8: System.out.println("above average Nice job"); break;
               case 7: System.out.println("average"); break;
               case 6:
               case 5:
               case 4:
               case 3:
               case 2:
               case 1:
               case 0: System.out.println("below average you should see the professor...to clarify the material presented in class..."); break;
               default: System.out.println("Invalid case"); break;              
               }
               break;
              
           }
           else{
               System.out.println("Error: You must enter an integer between 0 and 100");
               tries++;
           }
       }
   }

}

Output:

Please enter the grade between 0 and 100
101
Error: You must enter an integer between 0 and 100
Please enter the grade between 0 and 100
102
Error: You must enter an integer between 0 and 100
Please enter the grade between 0 and 100
