Method

Vectorclonevector(Vector vec)
Clones vector vec without cloning the components of the vector 
Vector result = new Vector();
for (int i = 0; i < vec.size(); i++)
    result.add(vec.elementAt(i));
return result;
StringcombineWithQuotes(Vector commands, int startAt)
combine With Quotes 
final StringBuffer Combined = new StringBuffer("");
if (commands != null)
    for (int commandIndex = startAt; commandIndex < commands.size(); commandIndex++) {
        String s = (String) commands.elementAt(commandIndex);
        if (s.indexOf(' ') >= 0)
            s = "\"" + s + "\"";
        Combined.append(s + " ");
return Combined.toString().trim();
booleanContains(Vector V, int[] elt)
Contains 
if (V == null || V.size() < 1)
    return false;
if (elt == null || elt.length != 2)
    return true;
for (int i = 0; i < V.size(); i++) {
    int[] R = V.elementAt(i);
    if (R[0] == elt[0] && R[1] == elt[1])
        return true;
...
VectorcopyVector(Vector V)
copy Vector 
final Vector V2 = new Vector();
for (int v = 0; v < V.size(); v++) {
    final Object h = V.elementAt(v);
    if (h instanceof Vector)
        V2.addElement(copyVector((Vector) h));
    else
        V2.addElement(h);
return V2;
voiddeleteLast(Vector list)
delete Last 
int lastIndex = list.size() - 1;
list.remove(lastIndex);
VectorenumerationToVector(Enumeration pEnumeration_)
Convert an enumeration to a vector. 
Vector vRetVal = new Vector();
while (pEnumeration_.hasMoreElements()) {
    Object pObject = pEnumeration_.nextElement();
    vRetVal.addElement(pObject);
return vRetVal;
StringgetCommaListFromVector(Vector sourceVector)
get Comma List From Vector 
StringBuffer strBuf = new StringBuffer();
for (int i = 0; i < sourceVector.size(); i++) {
    strBuf.append((i > 0 ? ", " : "") + sourceVector.elementAt(i));
return strBuf.toString();
int[][]getNonNullVectors(int[][] usageM)
get Non Null Vectors 
List<int[]> nonNullVectors = new ArrayList<int[]>();
for (int[] v : usageM) {
    boolean isNull = true;
    for (int i = 0; i < v.length; i++)
        if (v[i] > 0)
            isNull = false;
    if (!isNull)
        nonNullVectors.add(v);
...
booleanhasDuplicates(Vector v)
has Duplicates 
int i = 0;
int j = 0;
boolean duplicates = false;
for (i = 0; i < v.size() - 1; i++) {
    for (j = (i + 1); j < v.size(); j++) {
        if (v.elementAt(i).toString().equalsIgnoreCase(v.elementAt(j).toString())) {
            duplicates = true;
return duplicates;
booleanisContained(Object obj, Vector vect)
Check if object is contained in vector 
if (obj == null || vect == null) {
    return false;
return vect.contains(obj);
