Help with a java assignment

Question

I am stuck on some things and I can't find them in my book so here goes. I need to determine if a string is even or odd and then return letters from that word based on which it is.
I think i need to use a boolean for the even or odd (not for sure) and an if / else statement for the letters, but i am lost on some of the details. I should have to do some math to choose which letters i return, but not for sure on how to setup the math to use on a string.
can anybody help point me in the right direction with this
if you need more info on this let me know and i will try to explain it better.
thanks

Answer 1

i mean that I need to determine if the number of letters in a word is even or odd.
and here is the code the first one is my main class. I hope i did that right on the posting of the code
package wordstester;
import javax.swing.JOptionPane;
* @author christopher izatt
public class WordsTester {
     * @param args the command line arguments
    public static void main(String[] args) {
              // prompt the user to enter a string of their choice
      String wordChosen;
      wordChosen = JOptionPane.showInputDialog
          ("Please enter a word of your choice here");
      String middlePart;
      middlePart = Words.getMiddle(wordChosen);
      System.out.println("At the middle of " + wordChosen + " is: "
                 + middlePart);
package wordstester;
* @author christopher izatt
public class Words {
      Gets the middle character or character pair from this word
      when possible.
      @param word a word supplied by the method user
      @return the middle character (if the word length is odd) or
      middle two characters (if it is even), or the empty string if
      the word is empty, or null if it is null.
   public static String getMiddle(String word)
    private boolean word;
}
