StringasString(List commandLine)
as String 
String s = "";
for (String cmd : commandLine)
    s += (s.equals("") ? "" : " ") + cmd;

ListasStringList(Collection objects)
Returns a list of strings, where the strings are the result of calling String.valueOf( Object ) of each object in the given collection. 
List<String> list = new ArrayList<>();
for (Object object : objects) {
    list.add(String.valueOf(object));
return list;
ArrayListasStringList(Collection list)
Calls toString for each element and adds it to a new list. 
ArrayList<String> result = new ArrayList<String>(list.size());
for (Object o : list) {
    result.add(o.toString());
return result;
ListasStringList(Collection objects)
Returns a list containing the string representations of the given collection of objects. 
List<String> result = new ArrayList<String>();
for (Object o : objects) {
    result.add(String.valueOf(o));
return result;
ListasStringList(List coll)
Returns a string list representation of the given list. 
List<String> result = new ArrayList<>();
for (Object t : coll) {
    result.add(t.toString());
return result;
StringBuilderasStringList(Set attributes)
as String List 
final StringBuilder b = new StringBuilder();
Iterator<?> iterator = attributes.iterator();
while (iterator.hasNext()) {
    final Object o = iterator.next();
    b.append(o.toString());
    if (iterator.hasNext()) {

String[]convertListToStrArray(List list)

if (list != null) {
    int cnt = list.size();
    String[] strArray = new String[cnt];
    for (int i = 0; i < cnt; i++) {
        String str = (String) list.get(i);
        strArray[i] = new String(str);
    return strArray;

StringconvertListToString(List list)
convert List To String 
StringBuffer result = new StringBuffer();
String separator = "";
Iterator iter = list.iterator();
while (iter.hasNext()) {
    String line = iter.next().toString();
    result.append(separator);
    result.append(line);
    separator = "\n";
