int 和byte数组之间的转换

  public byte[] intToByte(int i) {

        byte[] abyte0 = new byte[4];

        abyte0[0] = (byte) (0xff & i);

        abyte0[1] = (byte) ((0xff00 & i) >> ;

        abyte0[2] = (byte) ((0xff0000 & i) >> 16);

        abyte0[3] = (byte) ((0xff000000 & i) >> 24);

        return abyte0;

    }

    public  static int bytesToInt(byte[] bytes) {

        int addr = bytes[0] & 0xFF;

        addr |= ((bytes[1] << & 0xFF00);

        addr |= ((bytes[2] << 16) & 0xFF0000);

        addr |= ((bytes[3] << 24) & 0xFF000000);

        return addr;

    }
