I have to do a project and I'm totally stuck.

It pops up an input window and say you type in "23"

It needs to print out:

3

2

0

Basically hundredths place but in reverse.

This is what I have so far:

Code:

String s = JOptionPane.showInputDialog("Enter an integer");
int num = Integer.parseInt(s); // turns a String into an int.
if num = negative
num = num * -1
else num = num * 1
int ones = num % 10;
int tens = (num % 10) - ones;
System.out.println(ones);
System.out.println(tens);
}
}

The "negative" is just a place holder until I find out how to say if a number is negative, times it by -1 to make it positive.

So far only "ones" is printed out right....I don't know how to get the tens place to print out correctly.

Halp me?
