Edit Question
Title
Body
I am writing this function for a J2ME application, so I don't have some of the more advanced / modern Java classes available to me. I am getting java.lang.ArrayIndexOutOfBoundsException on this. So, apparently either it doesn't like the way I've initialized the newChars array, or I'm not doing something correctly when calling System.arraycopy . /* * remove any leading and trailing spaces */ public static String trim(String str) { char[] chars = str.toCharArray(); int len = chars.length; // leading while ( (len > 0 ) && ( chars[0] == ' ' ) ) { char[] newChars = new char[] {}; // initialize empty array System.arraycopy(chars, 1, newChars, 0, len - 1); chars = newChars; len = chars.length; } // TODO: trailing return chars.toString(); }
