    Default ParseInt question

    static int parseInt(String s)
    Parses the string argument as a signed decimal integer.

    Java Code:
    public class Divider {
    	public static void main(String args[])
    			System.out.println("Before divison");
    			int i = Integer.parseInt(args[0]);
    			int j = Integer.parseInt(args[1]);
    			System.out.println("After divison");			
    		catch(ArithmeticException e) {
    			System.out.println("Arithmetic Exception");
    		catch(ArrayIndexOutOfBoundsException e) {
    			System.out.println("Array Index Out Of Bounds Exception.");
    		catch(NumberFormatException e) {
    			System.out.println("Number Format Exception");
    		finally {
    			System.out.println("Finally block");
    If I put in, for example, "1" and "hey" the program gives me a number format exception. I thought parseint returned the string AS an int? If so, why does it give me an exception?

    The "1" is okay, the "hey" isn't. It will parse the String as an int if the String is a number. And what a number is depends partially on the radix, but, when you don't designate one, the radix is 10 (i.e. normal decimal numbers).
