    Default TCP send byte

    Hallo,
    How can i do it that, Program will send byte? Main how do cycle while.
    For example String:
    Java Code:
    String line;
                while ((line = keyboard.readLine())!= null)
                {   
     
                    zapis.write(line);
                    zapis.newLine();                
                    zapis.flush();
     
                    System.out.println("Reading:"+line);
                }

    You may need to rephrase that so we can understand the question.

    OK sorry. I need to rebuild this cycle so Cycle work with byte.
    For example.

    Java Code:
    BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
    
    Security.addProvider(new BouncyCastleProvider());
                SecretKeySpec key = new SecretKeySpec("1234567891234567".getBytes("UTF-8"), "AES");
                    
                String nameAlgorithm = "AES/ECB/PKCS7Padding";
                Cipher cipher = Cipher.getInstance(nameAlgorithm);
                cipher.init(Cipher.ENCRYPT_MODE, key);
                
                byte[] encrypt = cipher.doFinal(keyboard.getBytes());
    
    byte line;
                while ((line = keyboard.readLine())!= null)
                {   
     
                    zapis.write(line);
                    zapis.newLine();                
                    zapis.flush();
     
                    System.out.println("Reading:"+line);
                }

    Nope, try again.
    What's a cycle? What's a zapis? What are you trying to do? What does your code actually do? Where is the problem? What is your specific question?

    Cycle = while. I need to do block cipher through TCP socket.
    Java Code:
    OutputStream out = socket.getOutputStream();
                BufferedWriter zapis = new BufferedWriter(new OutputStreamWriter(out));
