System.out.println()不写整个字符串！ [英] System.out.println() Not writing entire string!

问题描述

当我尝试获取字节流以使用String(responseBytes)写出字节时

When i try to get the bytestream to write out the bytes using String(responseBytes)

in_ = new DataInputStream(eiscpSocket_.getInputStream());
       byte [] responseBytes = new byte[64] ;
       int numBytesReceived = 0;

       numBytesReceived = in_.read(responseBytes);
       retVal = new String(responseBytes); //new String(responseBytes);
       System.out.println("received " + numBytesReceived + " bytes: \"" + responseBytes +"  "+ retVal + " \"" );

但是System.out.println("received" + numBytesReceived +"bytes:\""+ responseBytes +""+ retVal +" \")在retVal之后甚至整个retVal之后都不会打印任何内容.
我得到此输出

But System.out.println("received " + numBytesReceived + " bytes: \"" + responseBytes +" "+ retVal + " \"" ) does not print anything after retVal and not even the whole retVal.

I Get this output

received 46 bytes: "[B@137c60d  ISCP

使用此程序从我的onkyo接收者那里得到响应

为什么我不能打印我的字节响应?

using this program to get a response from my onkyo reciever

why cant i print my bytes response?

推荐答案

包围字节然后打印它们，为我解决了！

Looped the bytes and then printed them, solved it for me!
