    Are you intend to delete the last 2 characters that contain only "el" ?? , or you want to delete every last 2 characters and replace them with "em" ?
    if you want to replace every last 2 characters with "em", then you can do the following:
    public class StringReplacement {
       public static void main(String[] args) {
          if (args.length < 1) {
             System.err.println("Usage: java StringReplacement [string]\ne.g.: java StringReplacement Michael");
             System.exit(-1);
          }
     
          str = args[0].trim();
          str = str.replace(str.subSequence(str.length() - 2, str.length()), "em");
          System.out.println(str);
       }
    }

    If you're going to delete only last 2 characters that matched 'el', then here's the code:
          str = str.replaceAll("el$", "em");
          System.out.println(str);

    Anyway, REGEX is the most efficient way to handle string manipulation (just like what i did with the last example above).
