Alternatively, there is a convenient [MessageSender](./../libraries/java/api_reference#messagebuilder) helper class with chaining calls that prepares a message instance and broadcasts it over the network. {simple_message} **Output example**: ```string { message: { networkId: '14379272398717627559', parentMessageIds: [ '03ddc83fad172a322fb00fb4e449436e9d1117ff390879100647c650a30c2d52', '252798210fa9816f6fd40f1b19095da9f2dc88ae06fc4c0523a928a29d0d782e', 'a8e4f4cd49227068424ead8da187a48fdaa7ce8ffc4b9ac0ee2d5d3f2fcd7e70', 'dbbc8044bc624b3378e1dda83ab95f9be468b06a6a9806c76a70353182028cf9' ], payload: null, nonce: '9223372036854784215' }, messageId: '10dbee9cf3c58507725861b34ac711058dc13f709be1a6d21f1dc0af17b06379' } ``` - `messageId` is a unique id that refers to the given message in the network.
