[jdjlist] Re: Getting digits from an integer

[Greg Gent]

I beg to differ.  What get's printed out is:

 

digit = 1
digit = 2
digit = 3

Works fine.

 

looking at the logic:

digit = 1 is remainder of  321 / 10

divide 321 by ten and you're left with 32
digit = 2 is remainder if   32 / 10

divide 32 by ten and you're left with 3
digit = 3 is remainder of  3 / 10

divide 3 by ten and you're left with 0

exit the loop

That's my point. So what we get printed out is:

3, 2, 0  

...whereas Jeff wanted to get:

3, 2, 1 ??

Maybe I missed something here?

Dividing by 10 makes it 0.

what happens when number=1 on the final pass?

You need to do the following:

while (number != 0)
{
System.out.println ("digit = "+(number % 10));
number /= 10;
}

The >> is a binary shift operator.
