You do not need to use break in DEFAULT,

the best way to understand break is not to use it, eg

switch(var){
case a:
case b:
case c:
// do something
break;
case d:
// do something else
}

which means to do sth. in case of any of a,b,c but not d

        break;
   case b:
        System.out.println(“Penalty 5% :” + (x+x*0.05+x));

import java.util.Scanner;public class switchDemo {
    public static void main(String[] args) {
        Scanner inputDevice = new Scanner(System.in);        System.out.println(“Enter a number for a month”);        int iUserInput = inputDevice.nextInt();
                   switch (iUserInput) {            case 1: System.out.println ( “January” );     break;            case 2: System.out.println (“February”);      break;            case 3: System.out.println (“March”);         break;            case 4: System.out.println (“April”);         break;            case 5: System.out.println (“May”);           break;            case 6: System.out.println (“June”);          break;            case 7: System.out.println (“July”);          break;            case 8: System.out.println (“August”);        break;            case 9: System.out.println (“September”);     break;            case 10: System.out.println (“October”);       break;            case 11: System.out.println (“November”);      break;            case 12: System.out.println (“December”);      break;            default: System.out.println (“Invalid month”); break;                    }}}

can i use multiple choice in case of SELECT……CASE statement ? i.e.

select (expression)
{
case “a” or “A”:
system.println(“vovel”);
break;
case “a” or “A”:
system.println(“vovel”);
break;

case “e” or “E”:
system.println(“vovel”);
break;

default:
system.println(“Ashish you r wrong.”);

}

If you need to switch over a value that is a string you can embed it into an Enum:

public class Example{
enum Values { a, b, c }
public static void main(String[] args) {
Values v = Values.a;

switch() {
case a:
//TODO
break;
case b:
//TODO
break;
case c:
//TODO
break;
}
}
}
