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;
}
