Method

intlastIndexOfLetter(String string)
last Index Of Letter 
for (int i = 0; i < string.length(); i++) {
    char character = string.charAt(i);
    if (!Character.isLetter(character) ) {
        return i - 1;
return string.length() - 1;
intlastIndexOfNewline(CharSequence theChars, int aStart)
Returns index of the previous newline (or carriage-return/newline) in given chars starting at given char index. 
for (int i = aStart - 1; i >= 0; i--) {
    char c = theChars.charAt(i);
    if (c == '\n')
        return i - 1 >= 0 && theChars.charAt(i - 1) == '\r' ? (i - 1) : i;
    if (c == '\r')
        return i;
return -1;
...
intlastIndexOfNonWhitespace(final String src)
last Index Of Non Whitespace 
return lastIndexOfNonWhitespace(src, src.length(), 0);
intlastIndexOfOrdinal(String value, String part, int startIndex, int count, boolean caseSensitive)
Performs an ordinal string comparison. 
int valueLen = value.length();
int partLen = part.length();
int endIndex = startIndex - count + 1;
if ((valueLen == 0) && (startIndex == -1 || startIndex == 0))
    if (partLen != 0)
        return -1;
    else
        return 0;
...
intlastIndexOfPathSeparator(String str)
last Index Of Path Separator 
if (str == null)
    return -1;
int length = str.length();
for (int i = length - 1; i >= 0; i--) {
    char c = str.charAt(i);
    if (c == '/' || c == '\\') {
        return i;
return -1;
intlastIndexOfSeparator(String path)
This routine returns last index of separator in input param "path", and return it. 
return Math.max(path.lastIndexOf("/"), path.lastIndexOf("\\"));
intlastIndexOfUCL(String value)
last Index Of UCL 
for (int i = value.length() - 1; i >= 0; i--) {
    if (Character.isUpperCase(value.charAt(i))) {
        return i;
return -1;
intlastIndexOfUnnested(String str, char chr, String openBalance, String closeBalance)
last Index Of Unnested 
return lastIndexOfUnnested(str, chr, str.length() - 1, openBalance, closeBalance);
intlastIndexOfWhitespace(String s)
last Index Of Whitespace 
for (int i = s.length() - 1; i >= 0; i--)
    if (s.charAt(i) <= ' ')
        return i;
return -1;
