Description

The list of methods to do String Truncate are organized into topic(s).

Method

Stringtruncate(String input, int size)
truncates a String to the specified length 
if (input != null) {
    int len = input.length();
    if (len <= size) {
        return input;
    } else {
        return input.substring(0, size) + "...";
} else {
...
Stringtruncate(String message)
truncate 
if (message.lastIndexOf(".") < 500 && message.lastIndexOf(".") != -1) {
    return message.substring(0, message.lastIndexOf("."));
message = message.substring(0, 495);
if (message.lastIndexOf(".") < 500 && message.lastIndexOf(".") != -1) {
    return message.substring(0, message.lastIndexOf("."));
return message + "...";
...
Stringtruncate(String message, int length, boolean includeCount)
truncate 
if (message == null) {
    return null;
if (message.length() <= length) {
    return message;
String result = message.substring(0, length) + "...";
if (includeCount) {
...
Stringtruncate(String message, String substring)
This method is typically used to remove system-specific text from error messages, so that the error messages can be checked in a system-independent fashion. 
int i = message.indexOf(substring);
if (i < 0) {
    return message;
return message.substring(0, i + substring.length()) + "...";
Stringtruncate(String original, int number)

Keeps the 'number' first characters, and might be useful to keep your user's privacy :
 truncate("Hernandez", 3)
will produce: "Her"

If number is bigger than the size of the String, the whole string is kept :
 truncate("Hernandez", 24)
will produce: "Hernandez"

If number==0, the function returns an empty string.

if (number < 0) {
    throw new IllegalArgumentException("number :" + number + " is <0");
if (original == null) {
    throw new IllegalArgumentException("original string is null");
String newLastName = original.length() >= number ? original.substring(0, number) : original;
return newLastName;
...
Stringtruncate(String original, String ellipsis, int maxLength)
Truncates a String , and if necessary adds an ellipsis to the end of the string. 
if (original.length() > maxLength) {
    if (ellipsis == null) {
        ellipsis = "...";
    return original.substring(0, maxLength - ellipsis.length()) + ellipsis;
return original;
Stringtruncate(String originalString, int size)
If the size of the original string is larger than the passed in size, this method will remove the vowels from the original string. 
if (originalString.length() <= size) {
    return originalString;
String vowels = "AaEeIiOoUu";
StringBuilder newStringBufferTmp = new StringBuilder(originalString.length());
int counter = originalString.length() - size;
for (int index = (originalString.length() - 1); index >= 0; index--) {
    if (vowels.indexOf(originalString.charAt(index)) == -1) {
...
Stringtruncate(String s)
truncate 
return truncate(s, MAX_CONTENT_LENGTH);
Stringtruncate(String s)
truncate 
return truncate(s, 15);
Stringtruncate(String s, int begin, int end)
truncate 
if (isNullOrNone(s)) {
    return "";
if (begin < 0) {
    return "";
if (begin >= end) {
    return "";
