Basically, we are not directly using string in Java switch case because Java only permit to use Char and Integer variable directly in switch cases. So, in following example I have explained about how to handle String easily in Java switch case.

First of all possible string values are declared within a enum then in the application using that enum we can handle the string values in the switch case:

Example

public class Test{

public enum Day
{
     SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
     THURSDAY, FRIDAY, SATURDAY;
}
public static void main(String args[]) {

  String str="SUNDAY";

  switch (Day.valueOf(str))
  {
      case MONDAY:
      System.out.println("Day is Monday");
      break;

      case TUESDAY:
      System.out.println("Day is Tuesday");
      break;

      case WEDNESDAY:
      System.out.println("Day is Wednesday");
      break;

      case THURSDAY:
      System.out.println("Day is Thursday");
      break;

      case FRIDAY:
      System.out.println("Day is Friday");
      break;

      case SATURDAY:
      System.out.println("Day is Saturday");
      break;

      case SUNDAY:
      System.out.println("Day is Sunday");
      break;
  }
}
}
