Is there a string type in Java based on on an 8-bit byte array?

问题

Is there any string type/class in Java (standard or otherwise) that is based on an array of the 8-bit byte type, and not the 16-bit char type?

I really like the std::string type in C++, as it works very well with parsing base256 (binary) data...

I went ahead and wrote a little class that provides most of the features I need (below), but a better one would be appreciated!

public class stdstring extends Object {
    private byte [] bytedata;

    public stdstring() {
        bytedata = new byte[0];
    }

    public stdstring(byte[] bytes) {
        bytedata = bytes;
    }

    public stdstring(byte[] bytes, int offset, int length) {
        bytedata = new byte[length];
        System.arraycopy(bytes,offset,bytedata,0,length);
    }

    public stdstring(String string) throws UnsupportedEncodingException {
        bytedata = new byte[string.length()];
        bytedata = string.getBytes("ISO-8859-1");
    }

    public void assign(byte[] bytes) {
        bytedata = new byte[bytes.length];
        bytedata = bytes;
    }

    public void assign(byte[] bytes, int offset, int length) {
        bytedata = new byte[length];
        System.arraycopy(bytes,offset,bytedata,0,length);
    }

    public void assign(String string) throws UnsupportedEncodingException {
        bytedata = string.getBytes("ISO-8859-1");
    }

    public int length() {
        return bytedata.length;
    }

    public byte[] getBytes() {
        byte [] copy = new byte[bytedata.length];
        System.arraycopy(bytedata,0,copy,0,bytedata.length);
        return copy;
    }

    public byte[] getBytes(int offset, int length) {
        byte [] piece = new byte[length];
        System.arraycopy(bytedata,offset,piece,0,length);
        return piece;
    }

    public byte getByte(int offset) {
        byte b = bytedata[offset];
        return b;
    }

    public stdstring substring(int offset, int length) {
        stdstring sub = new stdstring(bytedata, offset, length);
        return sub;
    }

    public boolean equals(stdstring string) {
        if (bytedata.length != string.length()) { return false; }
        for (int i = 0; i < bytedata.length; ++i) {
            if (bytedata[i] != string.getByte(i)) { return false; }
        }
        return true;
    }
}
