Switch Case Statement

[Serkan Kilic]

Hi everyone.

I'm asked to a write JAVA switch...case statement that calculates Grades. My question is that how i could show this statement on the paper?

import java.util.Scanner;

public class Switch05
{
   public static void main(String[] args)
   {
      int score;
      String grade = "";
 
      Scanner in = new Scanner(System.in); 
 
      System.out.print("Enter your score here: ");
      score = in.nextInt();  

      switch ( score )
      {
         case 100:
         case 99:
         case 98:
         case 97:
         case 96:
         case 95:
         case 94:
         case 93:
         case 92:
         case 91:
         case 90:     grade = "A";  break;

         case 89:
         case 88:
         case 87:
         case 86:
         case 85:
         case 84:
         case 83:
         case 82:
         case 81:
         case 80:     grade = "B";  break;

         case 79:
         case 78:
         case 77:
         case 76:
         case 75:
         case 74:
         case 73:
         case 72:
         case 71:
         case 70:     grade = "C";  break;

         case 69:
         case 68:
         case 67:
         case 66:
         case 65:
         case 64:
         case 63:
         case 62:
         case 61:
         case 60:     grade = "D";  break;

         default:     grade = "F";  break;
      }

       System.out.println("Your grade is " + grade);
   }
}

Java, not JAVA. It's not an acronym.

What do you mean by "on the paper"?

Hi Serkan
I think you can also use the if (condition){} for this
If x =>90<=100 system.out,println("A") else

He specially said that he meeds to use switch statement -- I presume as an assignment.

But yes, a switch isn't the best way to accomplish this in the real world.

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		System.out.print("Enter your score here: ");
		int score = in.nextInt();
		String grade;
		switch (score / 10) {
			case 10:
			case 9: grade = "A"; break;
			case 8: grade = "B"; break;
			case 7: grade = "C"; break;
			case 6: grade = "D"; break;
			default: grade = "F"; break;
		}
		System.out.println("Your grade is " + grade);
	}

Looks shorter, huh? At least, it should fit A4 "paper"

This helped a lot. Thank you so much!!

And welcome to the Ranch

a variation of the same theme:

switch (score/10) {
case 10:
case 9 : System.out.println("A Outstanding!"); break;
case 8 : System.out.println("B Keep up the good work!"); break;
case 7 : System.out.println("C Room to improve!"); break;
case 6 : System.out.println("D See me after class!"); break;
case 5 : System.out.println("F MickyD is hiring!"); break;
}

But please everybody put case and break on lines by themselves.
