‘壹’ crc校验求java到啊

public class CRC16 { public static String crc16(String src,int len){
int crc = 0x0000FFFF;
short tc;
char sbit;
for(int i=0;i<len; i++){
tc = (short)(crc >>>8);
crc = ((tc ^ src.charAt(i)) & 0x00FF); for(int r=0;r<8;r++){
sbit = (char)(crc & 0x01);
crc >>>= 1; //�1�7�1�7�1�7�0�6�1�7�1�7�1�7�1�7�1�7�1�7�1�7�0�5λ
if(sbit != 0)crc =(crc^0xA001) & 0x0000FFFF; }
}
//Integer.toHexString(crc);
return Integer.toHexString(crc);
}
}

‘贰’ java的crc16校验，按指定多项式，求助

可以写的，参照附录那个算法用java代码实现即可。
