Note: Exception class must be inherited

class OutOfRange extends Exception{
   String message;
   OutOfRange(){
      message = new String("Please Enter No's between 0 and 100");
   }
   String toStr(){
      return message;
   }
}

public class MainCls{
   public static void main(String args[]){
      int input;
      String inputStr;
      InputStreamReader isr = new InputStreamReader(System.in);
      BufferedReader br = new BufferedReader(isr);
      
      inputStr = br.readLine();
      input = Integer.parseInt(inputStr);
      
      try{
         if(input < 0 || input > 100)
         throw new OutOfRange();
      }
      catch(OutOfRange e){
         System.out.println(e.toStr());
      }
      //Rest of code...
   }
}
