Method

StringshortenString(String orig, int charsToRemove)
shorten String 
if (charsToRemove <= 0) {
    return orig;
if (charsToRemove >= orig.length() - 1) {
    return orig.charAt(0) + "...";
int cut = orig.length() - charsToRemove;
int s1len = cut / 2 + cut % 2;
...
StringshortenString(String orig, int maxLength)
shorten String 
if (orig == null || orig.length() <= maxLength) {
    return orig;
return orig.substring(0, maxLength);
StringshortenString(String s, int maxLength)
If the string s is longer than maxLength , the string is cut and "..." 
if (s != null && s.length() > maxLength) {
    return s.substring(0, maxLength - 3) + "...";
} else {
    return s;
StringshortenString(String s, int requiredLength)
Shortens string to be no more than number of symbols specified 
if (s != null && s.length() > requiredLength) {
    s = s.substring(0, requiredLength + 1);
    int space = s.lastIndexOf(" ");
    int lineFeed = s.lastIndexOf("\n");
    int tab = s.lastIndexOf("\t");
    if (space > 0 || lineFeed > 0 || tab > 0) {
        int cut = space > lineFeed ? (space > tab ? space : tab) : (lineFeed > tab ? lineFeed : tab);
        s = s.substring(0, cut);
...
StringshortenString(String source, int minLength, int maxLength, String suffix)
Shorten the string to the specifed lenght. 
if (source == null || maxLength >= source.length()) {
    return source;
