send/read int in a client/server app

[dim_ath]

hi everyone!

could you please tell me what methods to use in order the clients be able to
send integers to server and server can read them?

Thanks!

package one;

import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {
	public static void main(String[] args) throws Exception{
		ServerSocket serverSocket = new ServerSocket(8080);
		Socket socket = serverSocket.accept();
		
		DataInputStream din = new DataInputStream(socket.getInputStream());
		System.out.println(din.readInt());
                socket.close()
	}
}


package one;

import java.io.DataOutputStream;
import java.net.Socket;

public class Client {
	public static void main(String[] args) throws Exception {
		Socket socket = new Socket("localhost" , 8080 );
		DataOutputStream out = new DataOutputStream(socket.getOutputStream());
		out.writeInt(5);
		socket.close();
	}
}

Run one.Server first followed by one.Client should print 5.
