finding the length in java

Mar 27th, 2006

Hi,

I'm creating a palindrome program. So far, I got that part. Now, I need to find out if the length of the integer (string) is less than 5 digits. If the length is less than 5, then don't proceed with the program. Please give your suggestions. Thanks!

Um...

if ( s.length() >= 5 ) {
  // Proceed
}

I'm here to prove you wrong.

Come, come now webmasts, surely if you have already successfully created a palindrome program you should know how to get the length.

-Or is this a GUI problem?

Anyway if you have further problems post this in the java forum.

Actually, I tried using the above code for finding the length, but it doesn't work. Anyways, I will try again. I get the following error:
