Description

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

Method

int[] intArray(double a, double b, double c)
Helper method to avoid lots of explicit casts in getShape().

return new int[] { (int) a, (int) b, (int) c };

Integer[] intArray(int len)
int Array

return new Integer[len];

int[] intArray(Integer... values)
int Array

int[] result = new int[values.length];
for (int i = 0; i < values.length; ++i) {
 result[i] = values[i];
return result;

int[] intArray(String data)
int Array

if (data == null || data.equals(""))
 return new int[0];
String[] split = data.split(" ");
int[] r = new int[split.length];
for (int i = 0; i < r.length; i++) {
 try {
 r[i] = Integer.parseInt(split[i]);
 } catch (NumberFormatException e) {
...

int[] intArrayConcat(int[] a, int[] b)
Return a new int[] which is the concatenation of a and b

int[] retval = new int[a.length + b.length];
System.arraycopy(a, 0, retval, 0, a.length);
System.arraycopy(b, 0, retval, a.length, b.length);
return retval;

boolean intArrayContains(int val, int[] array)
Returns true if int array 'array' contains value 'val'.

for (int i = 0; i < array.length; i++)
 if (val == array[i])
 return true;
return false;

boolean intArrayContains(int[] array, int key)
int Array Contains

for (final int i : array) {
 if (i == key) {
 return true;
return false;

boolean intArrayEquals(int[] a1, int[] a2)
Compare two int arrays for equality

return intArrayEquals(a1, 0, a2, 0, a1 == null ? 0 : a1.length);

int[] intArrayFromString(final String data)
int Array From String

final int[] result;
if (data.equals(CONFIG_EMPTY)) {
 result = null;
} else {
 final String[] split = data.split(CONFIG_SEPARATOR_ARRAY);
 result = new int[split.length];
 for (int i = 0; i < split.length; i++) {
 result[i] = Integer.parseInt(split[i].trim());
...

int[] intArrayFromString(String record)
int Array From String

return intArrayFromString(record, DEF_FIELD_DELIM);
