Method

int[]toIntArray(List list)
to Int Array 
int[] array = new int[list.size()];
for (int i = 0; i < list.size(); i++) {
    array[i] = list.get(i);
return array;
int[]toIntArray(List list)
Erstellt Integer-Array aus Liste 
int[] ret = new int[list.size()];
int i = 0;
for (Integer e : list) {
    ret[i++] = e.intValue();
return ret;
int[]toIntArray(List list)
to Int Array 
try {
    int[] ret = new int[list.size()];
    for (int i = 0; i < ret.length; i++) {
        ret[i] = list.get(i).intValue();
    return ret;
} catch (NullPointerException e) {
    return null;
...
int[]toIntArray(List list)
to Int Array 
if (isNullOrEmpty(list)) {
    return null;
int[] ints = new int[list.size()];
for (int i = 0; i < ints.length; i++) {
    ints[i] = list.get(i);
return ints;
...
int[]toIntArray(List list)
to Int Array 
int[] t = new int[list.size()];
for (int i = 0; i < t.length; i++)
    t[i] = list.get(i);
return t;
int[]toIntArray(List list)
This converts a list to it's primitive state. 
int[] array = new int[list.size()];
for (int i = 0; i < list.size(); i++) {
    array[i] = list.get(i);
return array;
int[]toIntArray(List list)
Converts a List of Integer to an int[] 
int[] res = new int[list.size()];
int index = 0;
Iterator iter = list.iterator();
while (iter.hasNext()) {
    Integer i = (Integer) iter.next();
    res[index++] = i.intValue();
return res;
...
int[]toIntArray(List values)
to Int Array 
int[] is = new int[values.size()];
for (int i = 0; i < is.length; i++) {
    is[i] = Integer.parseInt(values.get(i));
return is;
int[]toIntArray_impl(List i_list, int i_offset, int i_size)
to Int Arraimpl 
return toIntArray_impl(i_list, i_offset, i_size, new int[i_size]);
int[]toIntegerArray(final List list)
to Integer Array 
int[] array = new int[list.size()];
for (int i = 0; i < list.size(); i++) {
    array[i] = list.get(i);
return array;
