### Text Processing and JSON
```java
import org.codelibs.core.text.*;

// JSON utilities with proper escaping
String escaped = JsonUtil.escape("Hello \"World\" with special chars");
String unescaped = JsonUtil.unescape(escaped);

// Text tokenization
Tokenizer tokenizer = new Tokenizer("field1,field2,field3", ",");
while (tokenizer.hasMoreTokens()) {
    String token = tokenizer.nextToken();

    HashCode unused = sink.hash();
    sink.assertInvariants(8);
    sink.assertBytes(new byte[] {1, 2, 3, 4, 5, 6, 7, 8});
  }

  public void testChar() {
    Sink sink = new Sink(4);
    sink.putChar((char) 0x0201);
    HashCode unused = sink.hash();
    sink.assertInvariants(2);
    sink.assertBytes(new byte[] {1, 2, 0, 0}); // padded with zeros
  }

  public void testString() {
    Random random = new Random();

* Отправьте из них сообщения.
* Затем закройте одну из вкладок.

Это вызовет исключение `WebSocketDisconnect`, и все остальные клиенты получат следующее сообщение:

```

Приложение выше - это всего лишь простой минимальный пример, демонстрирующий обработку и передачу сообщений нескольким веб-сокет соединениям.

        }

        return username.charAt(0) + "***" + username.charAt(username.length() - 1);
    }

That will raise the `WebSocketDisconnect` exception, and all the other clients will receive a message like:

The app above is a minimal and simple example to demonstrate how to handle and broadcast messages to several WebSocket connections.
