switch case

public class EnumClass{
       
         static final  char A=10;
         static  final char B=11;
         static final  char C=33;
          public static void main(String args[]){

               final int B=98;
               final int C=97;
               switch((char)10){
                    default: System.out.print("Default ");
                    case A: System.out.print("Only A ");
                    case B: System.out.print("Only B ");
                    case C: System.out.println("Only C ");
               }
               
               
               
          }
     }

OUTPUT : Default Only A Only B Only C

It is taking int values declared in main. But I want to use char A ,char B declared as instance variables. Means I want Output as Only A Only B Only C . How can I use Char instance variables in switch case???

Banu,

If you convert (char)10, you'll get the ASCII equivalent of 10, which is neither A,B or C. Hence the compiler chooses "default", and prints its value. But then, since you haven't mentioned the break; statement after default, it continues to execute other statements in the switch case bundle [till end, or until it encounters a break], and hence you are getting this output.

Yet this does not address the question of using the static class varibles decalred. In this statement you are simply casting the local varibles to a char.

I tried this way:

public class EnumClass {
	
	static final char A = 10;
	static final char B = 11;
	static final char C=  33;
	
	public static void main(String[] args) {

                //you can declare anything else here

		
		final int A = EnumClass.A;
		final int B = EnumClass.B;
		final int C = EnumClass.C;
		
		switch(A){
		default: System.out.println("Default");
		case A: System.out.println("Only A");
		case B: System.out.println("Only B");
		case C: System.out.println("Only C"); 	
		
		
		}
		
	}

}

I recieved the following output:

Only A
Only B
Only C

What function do you give to your final local variables in your original code?
