Description

The list of methods to do Long Number Array Create are organized into topic(s).

Method

long[]toLongArray(final byte[] array)
to Long Array 
return toLongArray(array, 0, array.length);
long[]toLongArray(final int[] in)
Convert integer array to long array 
if (in == null)
    return null;
long[] out = new long[in.length];
for (int i = 0; i < in.length; i++) {
    out[i] = in[i];
return out;
Long[]toLongArray(final long[] longs)
Produces an array of Long objects from a long[]. 
final Long[] result = new Long[longs.length];
for (int i = 0; i < longs.length; i++) {
    result[i] = Long.valueOf(longs[i]);
return result;
long[]toLongArray(int... coordinates)
to Long Array 
long[] result = new long[coordinates.length];
for (int i = coordinates.length; --i != -1;) {
    result[i] = coordinates[i];
return result;
long[]toLongArray(Number[] array)
Turns the Number array into one consisting of primitive longs. 
long[] result;
int i;
result = new long[array.length];
for (i = 0; i < array.length; i++)
    result[i] = array[i].longValue();
return result;
long[]toLongArray(Object[] arr)
to Long Array 
long[] arr2 = new long[arr.length];
for (int i = 0; i < arr.length; i++) {
    arr2[i] = Long.parseLong(String.valueOf(arr[i]));
return arr2;
long[]toLongArray(String array)
Cast a string to an array of longs

String should have the format "[1,2,3]". 

if (array.length() == 2)
    return new long[0];
String[] cast = array.substring(1, array.length() - 1).split(",");
long[] result = new long[cast.length];
for (int i = 0; i < cast.length; i++) {
    result[i] = Long.valueOf(cast[i]);
return result;
...
long[]toLongArray(String str, String separator)
Converts a string of numbers to a long array 
String[] fields = str.split(separator);
long[] tmp = new long[fields.length];
for (int i = 0; i < tmp.length; i++)
    tmp[i] = Long.parseLong(fields[i]);
return tmp;
long[]toLongArray(String[] anArray)
to Long Array 
long[] output = new long[anArray.length];
for (int index = 0; index < anArray.length; index++)
    output[index] = Long.parseLong(anArray[index]);
return output;
