"A totally fresh and new approach to life itself emerges. Once again, you’re off to a good start, willing to do that little bit extra in your result-oriented frame of mind. It’s not the amount of effort but the results that matter to you. You also gain much in the depth of the romance and emoti"

Answer 1

In this method pass your string and last index till you want to truncate.

public String truncate(final String content, final int lastIndex) {

    if (content.charAt(lastIndex) != ' ') {
        result = result.substring(0, result.lastIndexOf(" "));
    }
    return result;
}
