Question

I would like to use Scanner to scan any number of integer then get the average. Before I stop, I would like to type \"END\".

The code below has: Exception in

Answer 1

You can simply add a try catch block as follows.

public static int scanaverage()
{
  System.out.println("Enter any number, type 'END' to exit");
  Scanner input = new Scanner(System.in);
  int total=0; 
  int count = 0;

  while (!(input.nextLine().equals("END")))
  {
   try{
    total += input.nextInt();
    count += 1;
    }catch(InputMismatchException e){

    }
  }
  return total / count;
}

I haven't test it.
