intcompareVersion(String va, String vb)
Compare version number, the format of version number should be X.X.X style. 
String[] vas = va.split("\\."); 
String[] vbs = vb.split("\\."); 
List<String> vaList = new ArrayList<String>();
for (int i = 0; i < vas.length; i++) {
    vaList.add(vas[i].trim().equals("") ? "0" : vas[i]); 
List<String> vbList = new ArrayList<String>();
for (int i = 0; i < vbs.length; i++) {
...
StringgetReverseShelfKey(String shelfkey)
given a shelfkey (a lexicaly sortable call number), return the reverse shelf key - a sortable version of the call number that will give the reverse order (for getting "previous" call numbers in a list) 
StringBuilder resultBuf = new StringBuilder(reverseDefault);
if (shelfkey != null && shelfkey.length() > 0)
    resultBuf.replace(0, shelfkey.length(), reverseAlphanum(shelfkey));
return resultBuf.toString();
Stringreverse(String aPackage)
reverse 
StringTokenizer tok = new StringTokenizer(aPackage, ".");
String ans = tok.nextToken();
while (tok.hasMoreTokens()) {
    ans = tok.nextToken() + "." + ans;
return ans;
Stringreverse(String s)
Reverse a string 
return new StringBuilder(s).reverse().toString();
Stringreverse(String text)
reverse 
char[] chars = text.toCharArray();
ArrayList<Character> list = new ArrayList<>();
for (int i = chars.length - 1; i >= 0; i--) {
    list.add(chars[i]);
int size = list.size();
chars = new char[size];
for (int i = 0; i < size; i++) {
...
Stringreverse(String word)
reverse 
char[] chars = word.toCharArray();
int size = word.length();
for (int li = 0, ri = size - 1; li < ri; li++, ri--) {

int index = 0;
for (int i = 0; i < string_len; i++) {
    final char ch = string.charAt(i);
    if (ch == ',') {
        if (i > index) {
            items.add(string.substring(index, i).trim());
...
StringreverseDelimited(String str, char separatorChar)
