Java Utililty Methods String Suffix

int suffix(final String source, final String target)
Find the length of a common suffix.

int pointermin = 0;
int pointermax = Math.min(source.length(), target.length());
int pointermid = pointermax;
while (pointermin < pointermid) {
 if (source.regionMatches(source.length() - pointermid, target, target.length() - pointermid,
 pointermid)) {
 pointermin = pointermid;
 } else {
...

String suffix(String fname)

int index = fname.lastIndexOf('.');
if (index < 0) {
 return "";
return fname.substring(index + 1).toLowerCase();

String suffix(String input, char delimiter)
Return the remainder of the string after the last occurrence of the delimiter char

if (input == null) {
 return null;
int pos = input.lastIndexOf(delimiter);
if (pos >= 0) {
 if (input.length() > pos + 1) {
 return input.substring(pos + 1);
 } else {
...

 return null;
int separatorIndex = name.lastIndexOf(separator);
if (separatorIndex < 0 || separatorIndex == name.length() - 1)
 return null;
else
 return name.substring(separatorIndex + 1);

String suffix(String name, String suffix)
suffix

return (suffix == null) ? name : name + suffix;

String suffix(String prefix, String path)
Return path relative to prefix (its suffix, but without leading slash).

if (!path.startsWith(prefix)) {
 return null;
int end = prefix.length();
if (path.length() > end && path.charAt(end) == '/') {
 end++;
return path.substring(end);
...

String suffix(String s, int delim)
Extract the portion of s after the last occurrence of the given delimiter.

int index = s.lastIndexOf(delim);
return (index == -1) ? s : s.substring(index + 1);

String suffix(String s, String suffix)
suffix

if (!s.endsWith(suffix)) {
 s = s + suffix;
return s;

String suffix(String str, int width, String with)

StringBuffer ret = new StringBuffer(str);
while (ret.length() < width)
 ret.append(with);
