I'm afraid you'll need to write a method of your own for that. It's very simple fortunately:public static int getLengthWithoutWhitespace(String s) {
    java.util.StringTokenizer st = new java.util.StringTokenizer(s, " \t\r\n");
    int counter = 0;
    while (st.hasMoreTokens()) counter += st.nextToken().length();
    return counter;
}This code is not tested... Here's another, a bit more reliable approach that simply passes through the characters of the string:public static int getLengthWithoutWhitespace2(String s) {
    int counter=0;
    for (int i=0; i < s.length(); i++)
        if (Character.isWhitespace(s.charAt(i))) counter++;
    return counter;
}
