Uncapitalizes all the whitespace separated words in a String.

StringBuffer buffer = new StringBuffer(strLen);
boolean whitespace = true;
for (int i = 0; i < strLen; i++) {
    char ch = str.charAt(i);
...

int strLen;

    return str;
return new StringBuffer(strLen).append(Character.toLowerCase(str.charAt(0))).append(str.substring(1))
        .toString();

return uncapitalize(str, null);
