// Create a new byte buffer with a capacity of 10 bytes ByteBuffer buffer = ByteBuffer.Allocate(10); // Put a string into the buffer String str = "Hello"; buffer.Put(Encoding.UTF8.GetBytes(str)); // Set the position back to the beginning of the buffer buffer.Rewind(); // Get the bytes from the buffer and convert back to a string byte[] bytes = new byte[str.Length]; buffer.Get(bytes); String convertedStr = Encoding.UTF8.GetString(bytes);In this example, we create a new ByteBuffer object that can hold up to 10 bytes. Then we put a string of bytes into the buffer, set the position back to the beginning of the buffer, and then get the bytes back out to convert them to a string again. This is just a simple example, but ByteBuffer can be used for more advanced tasks like reading and writing to files and sockets, as well as for serializing and deserializing data.
