Conversion between Java integers and byte arrays

The programs that you do sometimes need to be used,

Record the

public class Numberutil {/** * int integer to 4 byte array * * @param i * integer * @return byte array/public
		Static byte[] IntToByte4 (int i) {byte[] targets = new BYTE[4];
		TARGETS[3] = (byte) (I & 0xFF);
		TARGETS[2] = (byte) (I >> 8 & 0xFF);
		TARGETS[1] = (byte) (I >> & 0xFF);
		Targets[0] = (byte) (I >> & 0xFF);
	return targets; /** * Long Integer to 8-byte byte array * * @param lo * Long integer * @return byte array/public static byte[] Lon
		GToByte8 (Long lo) {byte[] targets = new BYTE[8];
			for (int i = 0; i < 8; i++) {int offset = (Targets.length-1-i) * 8;
		Targets[i] = (byte) ((Lo >>> offset) & 0xFF);
	return targets; /** * Short integer to 2-byte byte array * * @param s * Short integer * @return byte array/public static byte[] UN
		SignedShortToByte2 (int s) {byte[] targets = new BYTE[2];
		Targets[0] = (byte) (S >> 8 & 0xFF); TARGETS[1] = (byte) (S & 0xFF);
	return targets; /** * byte array converted to unsigned short integer * * @param bytes * byte array * @return short integer */public static int by
	Te2tounsignedshort (byte[] bytes) {return Byte2tounsignedshort (bytes, 0);  /** * byte array converted to unsigned short integer * * @param bytes * Byte array * @param off * start position * @return
		Short integer */public static int byte2tounsignedshort (byte[] bytes, int off) {int high = Bytes[off];
		int low = Bytes[off + 1]; Return (High << 8 & 0xff00) |
	(Low & 0xFF); /** * byte array converted to int integer * * @param bytes * Byte array * @param off * start position * @return int integer
		Number */public static int byte4toint (byte[] bytes, int off) {int b0 = Bytes[off] & 0xFF;
		int B1 = Bytes[off + 1] & 0xFF;
		int b2 = Bytes[off + 2] & 0xFF;
		int B3 = Bytes[off + 3] & 0xFF; Return (B0 << 24) | (B1 << 16) | (B2 << 8) |
