Hello i am new here, i want to ask about a problem of mine.
I have made a server code, so i can send commands from other program C#
i made that but my problem is when i start the java program because is Loading.
The Server is starting at the middle of it, so when i start it is stacking at BufferedRead.Readline so is not continiu at the other loading.
Can someone help me with it?

here the code:

package extensions.ServerManager.Server;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void loadSocket() 
    {
        ServerManagerSocket sms = new ServerManagerSocket();
        sms.handleConnection();
    }

    public void handleConnection() {
        System.out.println("Waiting for manager command...");

        //

BufferedReader's readLine() method is a blocking call, so it looks like your program is working as intended by Java, if not by you. When you call readLine(), your program is supposed to wait until there is a line to read from the input stream. If you don't want the program to wait, then don't call readLiine().

Can you please help me how should i do it. Just a tip not the whole code.

Is your test client using `BufferedWriter`? If yes, make sure you invoke the `flush()` method on the BufferedWriter after you are done with writing the message(comid in your case).

Yes thanks about that and i was thinking why is print it at the console :)
I just wanna know how i can read a line without block other calls
