Method

byte[]longTo4ByteArray(long n)
long To Byte Array 
byte[] bytes = Arrays.copyOfRange(ByteBuffer.allocate(8).putLong(n).array(), 4, 8);
assert bytes.length == 4 : bytes.length;
return bytes;
byte[]longToByteArray(long l)
Transform a long into a byte array 
ByteBuffer buffer = ByteBuffer.allocate(8);
buffer.putLong(l);
return buffer.array();
byte[]longToByteArray(long value)
long To Byte Array 
return ByteBuffer.allocate(Long.SIZE / Byte.SIZE).putLong(value).array();
byte[]longToByteArray(long value)
long To Byte Array 
byte[] byteArray = new byte[8];
ByteBuffer byteBuffer = ByteBuffer.wrap(byteArray);
LongBuffer longBuffer = byteBuffer.asLongBuffer();
longBuffer.put(0, value);
return byteArray;
byte[]longToByteArray(long[] array)
long To Byte Array 
byte[] result = new byte[array.length * 8];
ByteBuffer buffer = ByteBuffer.wrap(result);
for (int i = 0; i < array.length; i++) {
    buffer.putLong(array[i]);
return result;
byte[]longToBytes(final long value)
long To Bytes 
return ByteBuffer.allocate(BYTES_IN_LONG).putLong(value).array();
byte[]longToBytes(long aLong)
Convert a long to 8 bytes. 
return ByteBuffer.allocate(8).putLong(aLong).array();

long To Bytes 
buffer.putLong(0, l);
return buffer.array();
byte[]longToBytes(long l, int size)
long To Bytes 
ByteBuffer buf = ByteBuffer.allocate(size);
for (int i = 0; i < size; i++)
    buf.put(getNthByteFromLong(l, size - i - 1));
return buf.array();
byte[]longToBytes(long x)
long To Bytes
