Question

I am having trouble with the following programs and wasn't sure whether I did it right.

A. Write a program in java using a switch statement which asks the user for their letter grade then prints a message to the student according to the following chart:

Average		Message
A		Your work is outstanding!
B		You are doing good work!
C		Your work is satisfactory.
D		You need to work a little harder.
F		Please see me for extra help!

B. Write a program in java using a switch statement which gets a number from the user and then prints a message to the user according to the chart which follows. The number input must be between 1 and 10 inclusive.

Number	Message
1 or 3	Your number is a low odd number.
2 or 4	Your number is a low even number.
5	Your number is the middle odd number.
6	Your number is the middle even number.
7 or 9	Your number is a high odd number.
8 or 10	Your number is a high even number.

Any other number entered should receive a message telling the user that (s)he entered an invalid number.

Answer 1

Code for A:

import java.util.Scanner;
public class Main
{
   public static void main(String[] args) {
       Scanner scnr = new Scanner(System.in);
       char c=scnr.next().charAt(0);
       switch(c){
       case 'A':
       System.out.println("Your work is outstanding!");
       break;
       case 'B':
       System.out.println("You are doing good work!");
       break;
       case 'C':
       System.out.println("Your work is satisfactory.");
       break;
       case 'D':
       System.out.println("You need to work a little harder.");
       break;
       case 'F':
       System.out.println("Please see me for extra help!");
       break;
       default:
       System.out.println("invalid input!!");
       break;
       }
   }
}

Output for A:
