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

Method

longconvertLong(byte[] data, int offset)
This method uses a leading 1 byte[] This method converts a 4 byte integer that is stored in a byte[] and converts it to a decimal int 
byte[] target = new byte[4];
System.arraycopy(data, offset, target, 0, target.length);
return convertLong(target);
byte[]convertLong(long v, boolean isLE)
Convert long value to bytes arrays. 
byte[] bytes = new byte[8];
if (isLE) {
    bytes[0] = (byte) (v >>> 0);
    bytes[1] = (byte) (v >>> 8);
    bytes[2] = (byte) (v >>> 16);
    bytes[3] = (byte) (v >>> 24);
    bytes[4] = (byte) (v >>> 32);
    bytes[5] = (byte) (v >>> 40);
...
byte[]convertLong2FourBytes(long data)

result[1] = ((byte) ((0xFF0000 & data) >> 16));
result[0] = ((byte) ((0xFF000000 & data) >> 24));
return result;
byte[]convertLongAddressToBuf(long ipAddress)
convert Long Address To Buf 
byte[] result = new byte[4];
result[0] = (byte) ((ipAddress >> 24) & 0xFF);
result[1] = (byte) ((ipAddress >> 16) & 0xFF);
result[2] = (byte) ((ipAddress >> 8) & 0xFF);
result[3] = (byte) ((ipAddress >> 0) & 0xFF);
return result;
Long[]convertLongArray(long[] arr)
