    Default boxes

    I'm writing a client server UDP and it works though remaining bytes are represented as boxes which is something I don't want.
    import java.io.*;
    import java.net.*;
     
     
    public class PacketClientSendDemo{
    	public static void main(String[]args)throws IOException{
    	DatagramSocket socket = new DatagramSocket();
        String tot = "Hello Server";
    	byte[] data = tot.getBytes();
    	InetAddress addr = InetAddress.getLocalHost();
    	DatagramPacket packet = new DatagramPacket(data, data.length, addr,8797);
    	socket.send(packet);
     
    	packet.setData(new byte[1024]);
    	socket.receive(packet);
    	System.out.println(new String(packet.getData()));
     
    	}
    }
    import java.io.*;
    import java.net.*;
     
    public class PacketServerReceiveDemo{
    	public static void main(String[] args)throws IOException{
    	DatagramSocket socket = new DatagramSocket(8797);
    	DatagramPacket packet = new DatagramPacket(new byte[1024],1024);
    	socket.receive(packet);
    	System.out.println(new String(packet.getData()));
    	socket.send(packet);
    	}
    }

    Default Re: boxes

    I was wondering how I get output without the boxes representing empty bytes.

    Hello[][][], this is the kind of output I'm getting though the boxes are proper boxes.
