原文出处

终于整理完dbf文件读写的java源码，欢迎使用

修改以下代码

    private void init(inputstream inputstream)        throws jdbfexception    {        try        {            stream = new datainputstream(inputstream);            int i = readheader();            fields = new jdbfield[i];            int j = 1;            for(int k = 0; k < i; k++)            {                fields[k] = readfieldheader();                j += fields[k].getlength();            }

                       if(stream.read() < 1)                throw new jdbfexception("unexpected end of file reached.");            nextrecord = new byte[j];            try            {                //stream.readfully(nextrecord);                stream.read(new byte[263]);                stream.readfully(nextrecord);            }            catch(eofexception eofexception)            {                nextrecord = null;                stream.close();            }        }        catch(ioexception ioexception)        {            throw new jdbfexception(ioexception);        }    }

    private int readheader()        throws ioexception, jdbfexception    {        byte abyte0[] = new byte[16];        try        {            stream.readfully(abyte0);        }        catch(eofexception eofexception)        {            throw new jdbfexception("unexpected end of file reached.");        }        int i = abyte0[8];        if(i < 0)            i += 256;        i += 256 * abyte0[9];        i -= 264;        i = –i / 32;        //i = –i / 32;        //i–;        try        {            stream.readfully(abyte0);        }        catch(eofexception eofexception1)        {            throw new jdbfexception("unexpected end of file reached.");        }        return i;    }
