Description

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

Method

byte[] ensureCapacity(byte array[], int capacity)
ensure Capacity

if (capacity <= 0 || capacity - array.length <= 0)
 return array;
int newCapacity = array.length * 2;
if (newCapacity - capacity < 0)
 newCapacity = capacity;
if (newCapacity < 0) {
 if (capacity < 0) 
 throw new OutOfMemoryError();
...

byte[] ensureCapacity(byte[] bytes, int capacity)
Utility method used to ensure the capacity of byte array.

if (bytes.length < capacity) {
 int newsize = Math.max(1, bytes.length) << 1;
 bytes = Arrays.copyOf(bytes, newsize);
return bytes;

double[] ensureCapacity(final double[] array, final int minCapacity)
ensure Capacity

if (array.length < minCapacity) {
 return Arrays.copyOf(array, minCapacity);
return array;

T[] ensureCapacity(final T[] oldElements, final int requiredLength)
Ensure an array has the required capacity.

T[] result = oldElements;
if (oldElements.length < requiredLength) {
 result = Arrays.copyOf(oldElements, requiredLength);
return result;

Object[] reduceCapacity(Object[] arrays)
reduce Capacity

if (arrays == null) {
 return null;
int lastIndex = arrays.length - 1;
int length = arrays.length;
for (int i = lastIndex; i >= 0; i--) {
 if (arrays[i] == null) {
 length--;
