Method

voidaddTrimmed(StringBuffer stringbuffer, java.util.List list, int i)
add Trimmed 
int j = i + 1;
stringbuffer.setLength(j);
list.add(stringbuffer.toString());
stringbuffer.setLength(0);
voidaddTrimString(List aStringList, String aString)
add Trim String 
String tTrimedString = aString.trim();
if (tTrimedString.length() == 0)
    return;
aStringList.add(tTrimedString);
StringformatSampleText(final List lines, final int maxTrim)
Formats a section of sample text by removing leading whitespace characters up to a given maximum and by flattening lines into a single string. 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < lines.size(); i++) {
    sb.append(trimLeadingWhitespace(lines.get(i), maxTrim));
    if (i + 1 < lines.size()) {
        sb.append("\n");
return sb.toString();
...
ListgetTrimmedList(List listA)
Gets the trimmed list. 
ArrayList<String> newAList = new ArrayList<String>();
if ((listA != null) && (listA.size() > 0)) {
    for (String aStr : listA) {
        String val = trimToNull(aStr);
        if (null != val) {
            newAList.add(val);
return newAList;
ListsplitAndTrimCSVToList(String csv)
Return a List (never null) created from the csv string. 
if (isBlank(csv)) {
    return Collections.emptyList();
String[] tokens = csv.split(COMMA);
List<String> list = new ArrayList<String>();
for (String token : tokens) {
    list.add(token.trim());
return list;
ListsplitAsList(String source, char delimiter, boolean trim)
Splits a String into substrings along the provided char delimiter and returns the result as a List of Substrings.

List<String> result = new ArrayList<String>();
int i = 0;
int l = source.length();
int n = source.indexOf(delimiter);
while (n != -1) {
    if ((i < n) || ((i > 0) && (i < l))) {
        result.add(trim ? source.substring(i, n).trim() : source.substring(i, n));
    i = n + 1;
    n = source.indexOf(delimiter, i);
if (n < 0) {
    n = source.length();
if (i < n) {
    result.add(trim ? source.substring(i).trim() : source.substring(i));
return result;
ListstringToListTrim(String str, char delimiter)
creates a List from a String "List", trims empty values at start and end 
ArrayList list = new ArrayList();
int len = str.length();
if (len == 0)
    return list;
StringBuffer el = new StringBuffer();
boolean hasStart = false;
for (int i = 0; i < len; i++) {
    char c = str.charAt(i);
...
StringtoDelimitedString(List values, String delimiter, boolean trimValues)
to Delimited String 
if (values == null || delimiter == null) {
    return null;
StringBuilder stringBuilder = new StringBuilder();
for (int index = 0; index < values.size(); index++) {
    String value = values.get(index);
    String valueToUse = value;
    if (trimValues) {
...
ListtokenizeAndTrimToList(String value, String delimiter)
tokenize And Trim To List 
if (value == null) {
    return new ArrayList<String>(0);
value = value.trim();
String[] tokens = value.split(delimiter);
String token;
List<String> result = new ArrayList<String>(tokens.length);
for (int i = 0; i < tokens.length; i++) {
...
ListtoList(final String line, final boolean trimSpaces)
Parses a single line (String) of comma-separated values to a List . 
final ArrayList<String> results = new ArrayList<String>();
int i = 0;
final int length = line.length();
while (i < length) {
    final StringBuilder sb = new StringBuilder();
    if (trimSpaces) {
        while (i < length && Character.isWhitespace(line.charAt(i))) {
            ++i;
