public class Main {
    public static void main(String[] argv) {
        String inputString = "java2s.com";
        int truncateLength = 2;
        System.out.println(truncate(inputString, truncateLength));
    }/*  w  w  w. ja v a2 s . c o  m*/

     * E.g., "12345678" truncated to length 6 returns "123..."

        if (!(inputString.length() > truncateLength)) {
            return inputString;
