Is ArtihmeticException more specific than RunTimeException?

A good answer might be:

Yes.

A more compact way of showing the hierarchy is:

Exception

    IOException

    AWTException

    RunTimeException
        ArithmeticException
        IllegalArgumentException
            NumberFormatException
        IndexOutOfBoundsException
        Others

    Others

Don't memorize this diagram (for one thing, it is not complete). But look at it to see what it says. Here is a possibly incorrect program:

import java.lang.* ;
import java.io.* ;

public class DivisionPractice
{

  public static void main ( String[] a ) throws IOException
  {
    BufferedReader stdin = 
        new BufferedReader ( new InputStreamReader( System.in ) );
 
    String inData;
    int    num=0, div=0 ;


    try
    {
      System.out.println("Enter the numerator:");
      inData = stdin.readLine();
      num    = Integer.parseInt( inData );

      System.out.println("Enter the divisor:");
      inData = stdin.readLine();
      div    = Integer.parseInt( inData );

      System.out.println( num + " / " + div + " is " + (num/div) );
    }

    catch (NumberFormatException ex )
    {
      System.out.println("You entered bad data." );
      System.out.println("Run the program again." );
    }

    catch (ArithmeticException ex )
    {
      System.out.println("You can't divide " + num + " by " + div);
    }

  }
}
