java实现

[liujiuhua]

下面代码用java怎么实现
unsigned int CalCrc(char * buffer,unsigned int count)
{
unsigned int i,j;
unsigned int CrcValue = 0;
for(i=0;i<count;i++)
{

CrcValue = CrcValue ^ ( buffer[i] << 8 );

for (j = 0; j < 8; j++)
if (CrcValue & 0x8000)
CrcValue = (CrcValue << 1) ^ 0x1021;
else
CrcValue = CrcValue << 1;
}
return (CrcValue);
}

其实基本语法差不多 不过表现形式有点点不同而已 楼主只要稍微看一下 就很容易写出来了
