    Default TCP Problem

    Client:
    public static void updateTest(){
    		try{
    			Socket clientUpdate = new Socket(host, 1026);
    			BufferedReader in = new BufferedReader(new InputStreamReader(clientUpdate.getInputStream()));
    			DataOutputStream out = new DataOutputStream(clientUpdate.getOutputStream());
     
    			out.writeBytes(Version);
    			//Client those not write out Version to server when I add this
    			//System.out.println(in.readLine());
     
    			clientUpdate.close();
    		}catch(Exception e){
    			System.out.println(e);
    			System.out.println("Error: Test.updateTest()");
    		}
    	}
    Server:
    public static void update(){
    		try{
    			Socket connectUpdate = updateSocket.accept();
    			BufferedReader in = new BufferedReader(new InputStreamReader(connectUpdate.getInputStream()));
    			DataOutputStream out = new DataOutputStream(connectUpdate.getOutputStream());
     
    			String Data = in.readLine();
    			System.out.println(Data);
    			/*
    			 * When I add this to the code, the server doesnt even receive the string Data from the client
    			if(Data.equals("1.0.0.0")){
    				out.writeBytes("up to date");
    			}else{
    				out.writeBytes("Updating");
    			}
    			*/
     
    			connectUpdate.close();
    		}catch(Exception e){
    			System.out.println(e);
    			System.out.println("Error: update()");
    		}
    	}

    I have tried so many ways to fix this, like closing the in and outs at different times. I even tried using PrintWriter. I hav no clue why the server wont write back to the client.

    --- Update ---

    Please dont laugh at me, I fixed it, the shame.

    Having problems is nothing more than a sign of attempt.
    Fixing them is a sign of achievement.
    I see no shame
