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

Method

int[]getIntArray(ByteBuffer data, int offset, int length)
get Int Array 
if (length == 0) {
    return new int[0];
data.position(offset);
int[] intArray = new int[length / 2];
int index = 0;
while (index < intArray.length) {
    intArray[index++] = data.getShort();
...
intgetIntBE(ByteBuffer b, int start, int end)
get Int BE 
return (int) getLongBE(b, start, end);
intgetIntBE(final ByteBuffer b, final int start, final int end)
Computes a number whereby the 1st byte is the most significant and the last byte is the least significant. 
return (int) getLongBE(b, start, end);
ByteBuffergetIntByteBuffer(int id)
get Int Byte Buffer 
ByteBuffer buffer = ByteBuffer.allocate(intSize);
buffer.putInt(id);
buffer.flip();
return buffer;
intgetIntegerFromBuffer(ByteBuffer buffer, int offset, int size)
Gets integer from buffer 
int data = 0;
try {
    if (size == 1) {
        data |= buffer.get(offset);
    } else if (size == 2) {
        data |= buffer.getShort(offset) & 0xFFFF;
        data = Short.reverseBytes((short) data);
    } else if (size == 4) {
...
intgetIntFromBack(ByteBuffer bb)
get Int From Back 
int val = bb.getInt(bb.limit() - 4);
bb.limit(bb.limit() - 4);
return val;
IntegergetIntFromByteBuffer(ByteBuffer data)
int from ByteBuffer 
return getIntFromBytes(data.array());
intgetIntWithChecksum(ByteBuffer buffer, Adler32 checksum)
get Int With Checksum 
final int value = buffer.getInt();
checksum.update(value);
return value;
int[]readIntArray(ByteBuffer bb)
read Int Array 
int ints[] = null;
int size = bb.getInt();
if (size >= 0) {
    ints = new int[size];
    byte[] b = new byte[size * 4];
    bb.get(b);
    int l = 0;
    for (int i = 0; i < b.length; i += 4) {
...
int[]readIntArray(ByteBuffer buf)
No array length 
final int size = buf.getInt();
int[] arr = new int[size];
for (int i = 0; i < size; i++) {
    arr[i] = buf.getInt();
return arr;
