Java Socket Send Float Values

Java Socket Send float values or group of float values

Server:

class SampleServer {

public static void main(String args[]) throws Exception {

ServerSocket serverSocket = new ServerSocket(9080);

Socket socket = serverSocket.accept();

DataInputStream dataInSt = new DataInputStream(socket.getInputStream());

String string = "";

while (!string.equals("stop")) {

FloatBuffer buf = FloatBuffer.allocate(4);

byte[] bs = new byte[buf.capacity()*4];

dataInSt.read(bs);

FloatBuffer fb = ByteBuffer.wrap(bs).asFloatBuffer();

for(int i=0;i<fb.capacity();i++) {

System.out.println("Message: " + fb.get(i));

}

Thread.sleep(1000);

}

dataInSt.close();

socket.close();

serverSocket.close();

}

}

Client:

class SampleClient {

public static void main(String args[]) throws Exception {

Socket socket = new Socket("localhost", 9080);

DataOutputStream dataOuSt = new DataOutputStream(

socket.getOutputStream());

String string = "";

while (!string.equals("stop")) {

FloatBuffer input = FloatBuffer.allocate(4);

input.put(5.5f);

input.put(1.5f);

input.put(2.5f);

input.put(3.5f);

float[] f = input.array();

byte[] output = float2Byte(f);

dataOuSt.write(output);

dataOuSt.flush();

}

dataOuSt.close();

socket.close();

}

public static final byte[] float2Byte(float[] inData) {

int j = 0;

int length = inData.length;

byte[] outData = new byte[length * 4];

for (int i = 0; i < length; i++) {

int d = Float.floatToIntBits(inData[i]);

outData[j++] = (byte) (d >>> 24);

outData[j++] = (byte) (d >>> 16);

outData[j++] = (byte) (d >>> 8);

outData[j++] = (byte) (d >>> 0);

}

return outData;

}

}
