Java Utililty Methods Double Array Create

String[] fields = str.split(separator);
double[] tmp = new double[fields.length];
for (int i = 0; i < tmp.length; i++)
    tmp[i] = Double.parseDouble(fields[i]);
return tmp;

String[] values = value.split("\\s");
double[] array = new double[values.length];
for (int i = 0; i < values.length; i++) {
    values[i] = values[i].trim();
    if (values[i].length() > 0) {
        array[i] = Double.valueOf(values[i]);
return array;

double[] output = new double[anArray.length];
for (int index = 0; index < anArray.length; index++)
    output[index] = Double.parseDouble(anArray[index]);
return output;

int n = arr.length;
Double[] da = new Double[n];
int i = 0;
for (String e : arr) {
    da[i++] = Double.parseDouble(e);
return da;

double[] ret = new double[in.length];
for (int i = 0; i < in.length; i++)
    ret[i] = Double.parseDouble(in[i]);
return ret;

double[] outArray = new double[inArray.length];
int idx = 0;
for (String string : inArray) {
    outArray[idx] = Double.parseDouble(string);
    idx++;
return outArray;
