    return str;
if (separator == null) {
    return EMPTY;
int pos = str.indexOf(separator);
if (pos == -1) {
...
StringsubstringAfter(String str, String separator)
substring After 
if (isEmpty(str)) {
    return str;
} else if (separator == null) {
    return "";
} else {
    int pos = str.indexOf(separator);
    return pos == -1 ? "" : str.substring(pos + separator.length());
StringsubstringAfter(String str, String separator)

Gets the substring after the first occurrence of a separator. 

if (isEmpty(str)) {
    return str;
if (separator == null) {
    return EMPTY;

StringsubstringAfter(String string, String delim)
Returns the substring after the delimiter string, not including the delimiter string. 
int pos = string.indexOf(delim);
if (pos == 0)
    return string;
else if (pos > 0)
    return string.substring(pos + delim.length());
else
    return null;
StringsubstringAfter(String string, String delimiter)
substring After 
int pos = string.indexOf(delimiter);
return pos >= 0 ? string.substring(pos + delimiter.length()) : "";
StringsubstringAfter(String template, String toFind, String defaultTo)
Searches a given string ( template ) for a substring ( toFind ) and returns the portion of the string that follows the substring. 
int toFindLength = toFind.length();
int toFindOffset = template.indexOf(toFind);
int substringOffset = toFindOffset + toFindLength;
String returnValue;
if (toFindOffset == -1) { 
    returnValue = defaultTo;
} else {
    returnValue = template.substring(substringOffset);
...
StringsubstringAfter(String text, int index)
substring After 
if (index == INDEX_NOT_FOUND) {
    return EMPTY;
return text.substring(index + 1, text.length());
StringsubstringAfter(String text, String after)
Returns the portion of the overall string that comes after the first occurance of the given string. 
int indexOf = text.indexOf(after);
if (indexOf == -1) {
    return text;
return text.substring(indexOf + after.length());
StringsubstringAfter(String value, char delim)
substring After 
if (value == null) {
    return null;
int pos = value.indexOf(delim);
if (pos >= 0) {
    return value.substring(pos + 1);
return null;
...
StringsubstringAfterFirstIndex(String value)
Omits the first character and returns the remaining string. 
if (null == value || value.isEmpty()) {
    return "";
return value.substring(1);
