Stringtruncate(String str, int max)
Ensure that the given string is no more than 'max' characters long. 
return (str.length() > max) ? str.substring(0, max) : str;
Stringtruncate(String str, int max)
truncate 
if (str.length() <= max) {
    return str;
return str.substring(0, max);
Stringtruncate(String str, int maxLen)
truncates a string regardless of its length. 
if (str == null || str.length() < maxLen)
    return str;
if (maxLen < 0)
    return "";
return str.substring(0, maxLen);
Stringtruncate(String str, int maxSize)
Truncate a string to a max size. 
if (str == null) {
    return null;
if (str.length() <= maxSize) {
    return str;
return str.substring(0, maxSize);
Stringtruncate(String str, int maxSize)
truncate 
if (str != null && maxSize >= 0 && str.length() > maxSize) {
    return str.substring(0, maxSize);
} else {
    return str;
Stringtruncate(String str, int n)
Truncates a string and appends an ellipsis. 
return str.length() < n ? str : (str.substring(0, n) + "...");
Stringtruncate(String str, int size, boolean useEllipsis)
Truncate a string to a certain number of characters. 
String result = str;
if (str != null && str.length() > size) {
    result = str.substring(0, size);
    if (useEllipsis) {
        result += "...";
return result;
...
Stringtruncate(String str, int start, int end)
Returns the string truncated from the start index to end index. 
if (isNullOrEmpty(str)) {
    throw new IllegalArgumentException("Invalid String!, str: " + str);
if (start < 0 || start > end || end > str.length()) {
    throw new StringIndexOutOfBoundsException("Invalid Index!, start: " + start + ", endIndex:" + end);
StringBuilder sBuilder = new StringBuilder(str);
sBuilder.delete(start, end);
...
Stringtruncate(String str, String prefix, String suffix)
truncate 
if (str.startsWith(prefix) && str.endsWith(suffix))
    return str.substring(prefix.length(), str.length() - suffix.length());
return str;
Stringtruncate(String string, final int length)
truncate 
if (string.length() > length) {
    string = string.substring(0, length);
return string;
