String capitalize_chapterName = chapter_name.length()>1? chapter_name.substring(0,1).toUpperCase() + chapter_name.substring(1).toLowerCase() : chapter_name.toUpperCase();
it works fine for one word sattes
for northCarolina i need it to be North Carolina

you can capitalize the first letter using the method that you stated, for other letters, you could use the method isUpper in java.lang.Character.
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Character.html


create a string buffer and then loop through the string, character by character, and if the letter is uppercase, then add a space and the letter to the buffer, otherwise just add the letter.

using the character class, you can even perform more fine tunning like removing whitespaces, determining if the character is a letter or a digit, etc.

try:

s = s.replaceAll("([A-Z])", " {1}");

java regex might be helpful here:

import java.util.regex.*;

public class test
{
  public static void main(String args[]) {
    String state = "northCarolina";
    Pattern p = Pattern.compile("[A-Z]"); // Matching all Upper Charaters...
    Matcher m = p.matcher(state);
    while (m.find()) {
      state = state.substring(0,m.start()) + " " + state.substring(m.start());  // Add one space to all the Upper Characters..
    }
    state = state.substring(0,1).toUpperCase() + state.substring(1); // Convert the First Character to Upper...
    System.out.println(state);
  }
}
