Take these examples I would like to get the John The first word after the space, but it might not be until the end, it can be until a non alpha character. How would this be in Java 1.5?

You can use regular expressions and the Matcher class: Result:

APIzation

String s = "Smith-Crane John-Henry";
Pattern pattern = Pattern.compile("\\s([A-Za-z]+)");
Matcher matcher = pattern.matcher(s);
if (matcher.find()) {
    System.out.println(matcher.group(1));
}

package com.stackoverflow.api;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Human2961537 {

  public static String retrieveSecondWord(String s) {
    //https://stackoverflow.com/a/2961537
    Pattern pattern = Pattern.compile("\\s([A-Za-z]+)");
    Matcher matcher = pattern.matcher(s);
    if (matcher.find()) {
      System.out.println(matcher.group(1));
    }
    return matcher.group(1);
  }
}
