I have to write a program that reads in an integer and breaks it into a sequence of individual digits in reverse order. For example, the input 16384 is displayed as

4
8
3
6
1

You may assume that the input has no more than five digits and is not negative.

Define a class DigitExtractor:

public class DigitExtractor
{
.......


}

Ok. What how am I suppose to write this? He wants a DigitExtractor.java file and a DigitExtractorTest.java file.

Where am I suppose to put the input code at? Help me once more. Thanks.


We have to use JOptionPane, so I guesss we import javax.swing.JOptionPane;

PLEASE Help! I'm still stuck and its due tomorrow!!!

    Note that the following holds:
    [code]
    number % 10 = last digit
    (number - last digit) / 10 = number with last digit removed
    [/code]

    This should get you started...

    import javax.swing.JOptionPane;


    public class DigitExtractor{


    public static void main(String[] args){
    String reply = JOptionPane.showInputDialog( null, "Enter :" );
    int number = Integer.parseInt(reply);
    if (number > 99999){
    System.out.print("You have entered an incorrect number");
    }
    char[] result = reply.toCharArray();

    for(int i = 4; i>-1; i--){
    System.out.println(result[i]);
    }

    }

    }
