Is string in switch case is allowed in JAVA as in C# ?

 
  • JAVA SE 06 or earlier :-   Not Allowed
  • JAVA SE 07 or later    :-    Allowed

Use of string in switch case is allowed in Java from version 1.7, i.e. if you are using Java version 7 or later, you may use string in switch case if needed.

Consider this example :

class StringCaseDemo
{
 public static void main(String args[])
 {
  String country=args[0];// value specified by user (comm-line args)
     switch (country) 
    {
     case  "india":
               System.out.println( "Country Code is +91  ");
               break;
     case  "usa":
               System.out.println( "Country Code is +1  ");
               break;
     case  "italy":
               System.out.println( "Country Code is +39  ");
               break;
     case  "spain":
               System.out.println( "Country Code is +34  ");
               break;
     default: 
             System.out.println( "Invalid Country Code ");
    }  // end of switch
  }
} 

The above code works well with Java 1.7 (or later). But Java versions < 1.7 gives compile-time error.
