Description

The list of methods to do List Value Add are organized into topic(s).

Method

Listadd(List vector, int[] sparseVector)
The addition of two vectors, one of which is a sparse vector with value 1. 
List<Integer> result = new ArrayList<Integer>(vector);
for (int offset : sparseVector) {
    if (offset == -1) {
        continue;
    result.set(offset, result.get(offset) + 1);
return result;
...
voidadd(List list, Object[] array)
add 
list.addAll(Arrays.asList(array));
voidadd(List data, Object... values)
add 
data.add(values);
voidadd(List> target, E value)
add 
int dbsize = target.size();
switch (dbsize) {
case 1:
    target.get(0).add(value);
    break;
default:
    throw new IllegalArgumentException();
ArrayListadd(List a, List b)
add 
ArrayList<String> ret = new ArrayList<String>();
for (String s : a) {
    ret.add(s);
for (String s : b) {
    ret.add(s);
return ret;
...
booleanadd(List list, String value)
Adds the value to the list if neither null nor empty string. 
if (value == null)
    return false;
if (value.length() == 0)
    return false;
list.add(value);
return true;
Listadd(List aList, T anObj)
Adds an object to the given list and returns list (creates list if missing). 
if (aList == null)
    aList = new Vector();
aList.add(anObj);
return aList;
voidadd(List aList, T anObject)
If @List is Empty inizialize it to a new @ArrayList 
if (aList == null) {
    aList = new ArrayList<T>();
aList.add(anObject);
voidadd(List current, T toAdd)
Generic addition of an item to a List (without repeats) -- used to accommodate ObservableLists in front-end 
for (int i = 0; i < current.size(); i++) {
    if (current.get(i).equals(toAdd)) {
        current.remove(i);
        i--;
current.add(toAdd);
voidadd(List list, int i, T v)
Adds the element i in list, as in List#add(int,Object) , but independently on list.size(). 
if (i <= list.size())
    list.add(i, v);
else
    set(list, i, v);
