Thread: Java socket

Hey. i have this problem where my java socket client instantlly shuts down after i run it. heres the code:

package basic;
 
import java.io.*;
import java.net.*;
 
public class LoginClient {
    public static void main(String argv[]) throws Exception {
        String sentence;
        String modifiedSentence;
        BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));
 
        Socket clientSocket = new Socket("localhost", 6789);
        DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());
        BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
 
        sentence = inFromUser.readLine();
        outToServer.writeBytes(sentence + '\n');
        modifiedSentence = inFromServer.readLine();
        System.out.println(modifiedSentence);
    }
}

I dont understand what is wrong. im begginer.

What do you want the program to do after it prints out the modifiedSentence?

I dont really know. I took this code from the internet. tryed to to while(true) loop but it still instantlly exitted.
