Method

booleancontains(List aList, Object anObj)
Returns whether list contains given object (accepts null list). 
return aList != null && aList.contains(anObj);
booleancontains(List list, Object obj)
Checks if the given list contains a specific object value by comparing the string version. 
for (Object entry : list) {
    if (entry.toString().equals(obj.toString()))
        return true;
return false;
booleancontains(List lsttor, Object val)
contains 
for (int i = 0; i < lsttor.size(); i++)
    if (lsttor.get(i).equals(val))
        return true;
return false;
booleancontains(List list, Object element, int begin, int end)
contains 
return indexOf(list, element, begin, end) != -1;
booleancontains(List objects, Object object)
contains 
boolean contains = objects.contains(object);
return contains;
booleancontains(List listOfArrays, A[] array)
Checks if the given list of arrays contains an array that is equal to array by the definition of Arrays.equal(..) (both arrays must have the same number of elements, and every pair of elements must be equal according to Object.equals). 
for (A[] curArray : listOfArrays) {
    if (Arrays.equals(curArray, array))
        return true;
return false;
booleancontains(List list, int[] arr)
contains 
for (int[] arr2 : list) {
    if (arr.length != arr2.length)
        continue;
    for (int i = 0; i < arr2.length; i++)
        if (arr2[i] != arr[i])
            continue;
    return true;
return false;
booleancontains(List list, List> listOfLists)
contains 
for (List<String> cur : listOfLists) {
    if (isSame(list, cur)) {
        return true;
return false;
booleancontains(List list, String str, boolean bcaseSensitive)
contains 
if (list == null || list.isEmpty() || isNullOrEmpty(str))
    return false;
if (bcaseSensitive) {
    return list.contains(str);
for (String s : list) {
    if (s.equalsIgnoreCase(str))
        return true;
...
booleancontains(List list, String string)
This method checks if the list contains the given string (case sensitive). 
if (isNotEmpty(list)) {
    for (String item : list) {
        if ((item != null && string != null && item.compareTo(string) == 0)
                || (item == null && string == null)) {
            return true;
return false;
