Java Utililty Methods String Trim Right

int len = str.length();
char[] val = str.toCharArray();
int count = len;
while (len > 0 && (val[len - 1] <= ' ')) {
    len--;
return (len < count) ? str.substring(0, len) : str;

return str.replaceAll("\\s+$", "");

int end = str.length() - 1;
if (null == charList)
    for (int i = end; i >= 0; i--)
        if (Character.isWhitespace(str.charAt(i)))
            end--;
        else
            break;
else
...

if (str == null)
    return defaultValue;
int len = str.length();
while ((0 < len) && (str.charAt(len - 1) <= ' ')) {
    len--;
return (len < str.length()) ? str.substring(0, len) : str;

if (isNull(str) || isNull(suffixs))
    return str;
int i = str.length() - 1;
for (; i >= 0; i--) {
    if (suffixs.indexOf(str.charAt(i)) == -1)
        break;
return str.substring(0, i + 1);
...

if (string.endsWith(end)) {
    string = string.substring(0, string.length() - end.length());
return string;

if (text == null) {
    return EMPTY;
int i = 0;
int j = text.length();
while ((i < j) && (text.charAt(j - 1) == c)) {
    j--;
return (j < text.length()) ? text.substring(i, j) : text;

if (value == null) {
    return null;
int index = value.length();
while (index > 0 && isWhitespace(value.charAt(index - 1))) {
    index--;
return value.substring(0, index);

String result = nvl(value).trim();
if (result.length() > maxLength) {
    result = result.substring(0, maxLength);
return result;

return rTrim(nz(o));
