Question

我有一个ByteArrayOutputStream，可用来编写如下内容：这些是

（0,0,0,0,10,84,101,115,116,58,32,109,97,105,101）

转换为以下字符：

 [B@61dc03ec

这是我的写法：

    baos.write(zeroByte);
    baos.write(lengthBytes);
    baos.write(messageBytes);
    byte[] c = baos.toByteArray();

这是我在写的东西：

 int messageLength=EchoRequest.newBuilder()
            .setMessage("Test" + ": " +    Thread.currentThread().getName())
            .build().getMessageBytes().toByteArray().length;

        byte[] lengthBytes =   ByteBuffer.allocate(4).putInt(messageLength).array();

       byte[] zeroByte = {0};

      byte[] messageBytes = EchoRequest.newBuilder()
            .setMessage("Test" + ": " +  Thread.currentThread().getName())
            .build().getMessageBytes().toByteArray();
