Description: CRC16算法的Java实现，使用方法如下：
CRC16 crc16 = new CRC16()
byte[] b = new byte[] {
// (byte) 0xF0,(byte)0xF0,(byte)0xF0,(byte)0x72
(byte) 0x2C, (byte) 0x00, (byte) 0xFF, (byte) 0xFE,
(byte) 0xFE, (byte) 0x04, (byte) 0x00, (byte) 0x00,
(byte) 0x00, (byte) 0x00 }
for (int k = 0 k < b.length k++) {
crc16.update(b[k])
}
System.out.println(Integer.toHexString(crc16.getValue()))
System.out.println(Integer.toHexString(b.length))

System.out.println(Integer.toHexString(b.length)) -CRC16 algorithm realize Java, use the following method: CRC16 crc16 = new CRC16 () byte [] b = new byte [] (//(byte) 0xF0, (byte) 0xF0, (byte) 0xF0, (byte) 0x72 (byte ) 0x2C, (byte) 0x00, (byte) 0xFF, (byte) 0xFE, (byte) 0xFE, (byte) 0x04, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00) for ( int k = 0 k
