Sockets- Java not receiving the bytes in proper encoding

Question

I am using sockets and implementing a Java server and a c++ client. The client is sending server a class. Java server receives it as array of bytes but after that it is not converting it back into the class members right. I have looked a lot but I guess I don't really know what to look for. Here are the parts of the code, complete code is quite big

Client C++

IntVal temp; 
Set(temp,values);


int tempp;
tempp=send(s_id,&temp,sizeof(temp),0);
if(tempp==-1)
{
    printf("Sending Error \n");
}

"IntVal Class" has 7 to 8 float values and no member function.

Server Java

public static void main(String[] args) throws IOException {
        // TODO code application logic here
         Values values=new Values();
         gui display=new gui();
         display.setVisible(true);
        ServerSocket Sock=new ServerSocket(9090);
        try{
            while(true){
                System.out.println("Waiting");
                Socket socket=Sock.accept();

                    System.out.println("Connected");
                  InputStream ins=socket.getInputStream();
                    InputStreamReader insr= new InputStreamReader(ins);
                    BufferedReader br=new BufferedReader(insr);

                    byte[]Array=br.readLine().getBytes("UTF-8");
                   // values.SetValues(Array);
                    //display.SetValues(values);

                    values.tWidth=Array[0];
                    values.waterLevel=Array[4];
                    values.camHeight=Array[8];
                    values.camViewAngleY=Array[12];
                    values.camViewAngleX=Array[16];
                    values.distFromCamBank=Array[20];
                    values.distTwoPoints=Array[24];
                    values.AvgVelocity=Array[28];
                    values.crossSecArea=Array[32];
                    values.Flow=Array[36];
                    values.camTiltAngle=Array[40];
                    values.aboveWater=Array[44];
                    System.out.println(values.tWidth);
                    System.out.println(values.waterLevel);
                    socket.close();
                }

        }
        finally{
            Sock.close();
        }


    }
}

Here Class Values is equivalent to IntVal class in c++ client. As you can see I am only checking with first two values, They display Garbage values. Please point me in right direction that what is wrong here.

Answer 1

You are encoding and decoding the bytes yourself so it's you who is to blame for this, not Java. Use an InputStream, not a Reader, and process the bytes directly.
