for (String search : searchList) {
    if (value != null && value.equals(search)) {
        return true;
    } else if (value == null && search == null) {
        return true;
return false;
...
StringstringFromLines(List lines)
string From Lines 
StringBuffer buf = new StringBuffer();
for (String line : lines) {
    buf.append(line).append('\n');
return buf.toString();
StringstringFromList(List list)
Converts (any) list into a string, useful with the WebUtils#readURL(String) method 
String val = "";
for (Object o : list)
    val = val + String.valueOf(o) + "\n";
return val;
StringstringfyList(List ls)
stringfy List 
if (ls.isEmpty())
    return "";
String res = "[";
boolean first = true;
for (Object l : ls) {
    if (!first)
        res += ",";
    res += " " + l.toString();
...
Stringstringify(List entries)
stringify 
if (entries == null || entries.isEmpty()) {
    return "";
StringBuilder stb = new StringBuilder();
for (T entry : entries) {
    stb.append(String.valueOf(entry));
    stb.append(",");
return stb.substring(0, stb.length() - 1);
StringstringifyList(List items)
stringify List 
StringBuffer buf = new StringBuffer();
for (String s : items) {
    buf.append(s);
    buf.append(ITEM_SEP);
return (buf.toString());
StringstringList(String prefix, String suffix, String separator, Object... objects)
Constructs a list of items in a string form using a prefix and suffix to denote the start and end of the list and a separator string in between the items. 
StringBuilder builder = new StringBuilder(prefix);
for (int i = 0; i < objects.length; i++) {
    builder.append(objects[i].toString());
    if (i < objects.length - 1) {
        builder.append(separator);
builder.append(suffix);
...
StringstringList2String(final String suffix, final List list)
string List String 
if (list == null || list.isEmpty()) {
    return null;
StringBuilder builder = new StringBuilder("");
for (int i = 0; i < list.size(); i++) {
    String value = list.get(i);
    if (value != null && !"".equals(value)) {
        if (i < (list.size() - 1)) {
...
StringstringList2String(List list, String separator)
Return list of strings in a single string separated by a separator string. 
String ret = "";
for (String s : list) {
    ret += s + separator;
return ret.substring(0, ret.length() - separator.length());
booleanstringListEquals(List left, List right)
Tests if two arrays of strings have the same members irrespective of order. 
if (left.size() != right.size()) {
    return false;
if (left.size() == 0) {
    return true;
List<String> copyOfLeft = new ArrayList<String>(left);
List<String> copyOfRight = new ArrayList<String>(right);
