Explanation / Answer

1. Move entire switch block inside try{} block, this will ensure program will run even if exception is thrown on any one run.

2. Add catch block following to try as shown below

catch(ArithemeticException ex){ // This will handle arithematic exceptions

System.out.println(ex.Message);

}

catch(Exception ex){ // This is to handle all exceptions

System.out.println(ex.Message);

}

Note:// Add appropriate exception packages to use this
