字节数组[]到字节在Java中可能吗？

Question

I know in java we can't deal with bit directly, I want to know how can we convert an byte array[] to byte. Such that

String bytestr="00000011";
byte[] noofbytes=bytestr.getBytes();
byte convbyte=(noofbytes[]) to byte

Is it possible ? does any one have any idea ? Thanks.

Answer 1

I think you mean bits , not bytes.

String bitstr = "00000011";
byte convbyte = Byte.parseByte(bitstr, 2);

The , 2 tells it that you're parsing a binary (base 2) string; the default would be decimal (base 10).
