Method

float[] toFloatArray(Float[] list)
to Float Array

float[] array = new float[list.length];
for (int i = 0; i < array.length; i++)
 array[i] = list[0];
return array;

float[] toFloatArray(java.util.List list, float[] res)
to Float Array

if (res == null)
 res = new float[list.size()];
int i = 0;
for (Float e : list)
 res[i++] = e.floatValue();
return res;

float[] toFloatArray(List list)
to Float Array

float[] array = new float[list.size()];
Iterator<Double> ints = list.iterator();
int idx = 0;
while (ints.hasNext()) {
 Double value = ints.next();
 array[idx++] = value.floatValue();
return array;
...

float[] toFloatArray(List list)
to Float Array

if (isNullOrEmpty(list)) {
 return null;
float[] floats = new float[list.size()];
for (int i = 0; i < floats.length; i++) {
 floats[i] = list.get(i);
return floats;
...

float[] toFloatArray(List list)
to Float Array

try {
 float[] ret = new float[list.size()];
 for (int i = 0; i < ret.length; i++) {
 ret[i] = list.get(i).floatValue();
 return ret;
} catch (NullPointerException e) {
 return null;
...

float[] toFloatArray(List list)
Turns the Float list into a float array.

float[] result;
int i;
result = new float[list.size()];
for (i = 0; i < list.size(); i++)
 result[i] = list.get(i);
return result;

float[] toFloatArray(List list)
This converts a list to it's primitive state.

float[] array = new float[list.size()];
for (int i = 0; i < list.size(); i++) {
 array[i] = list.get(i);
return array;

float[] toFloatArray(List values)
to Float Array

float[] fs = new float[values.size()];
for (int i = 0; i < fs.length; i++) {
 fs[i] = Float.parseFloat(values.get(i));
return fs;

List toFloatList(List list)
Converts a list of integers to a list of floats.

List<Float> floatList = new ArrayList<Float>();
for (Integer val : list) {
 floatList.add(val.floatValue());
return floatList;
