#Sample use ##Very simple funds transfer

This is a simple transfer operation of 1 BTS from account bilthon-15 to bilthon-5

// Creating a transfer operation
TransferOperation transferOperation = new TransferOperationBuilder()
        .setTransferAmount(new AssetAmount(UnsignedLong.valueOf(100000), new Asset("1.3.0")))
        .setSource(new UserAccount("1.2.143563"))       // bilthon-15
        .setDestination(new UserAccount("1.2.139313"))  // bilthon-5
        .setFee(new AssetAmount(UnsignedLong.valueOf(264174), new Asset("1.3.0")))
        .build();
        
// Adding operations to the operation list
ArrayList<BaseOperation> operationList = new ArrayList<>();
operationList.add(transferOperation);

// Creating a transaction instance
Transaction transaction = new Transaction(sourcePrivateKey, null, operationList);

From here on, it is just a matter of creating a websocket connection and using a custom handler called TransactionBroadcastSequence in order to broadcast it to the witness node.

// Setting up a secure websocket connection.
SSLContext context = null;
context = NaiveSSLContext.getInstance("TLS");
WebSocketFactory factory = new WebSocketFactory();
factory.setSSLContext(context);

WebSocket mWebSocket = factory.createSocket(FULL_NODE_URL);

mWebSocket.addListener(new TransactionBroadcastSequence(transaction, new Asset("1.3.0"), listener));
mWebSocket.connect();

The provided listener is an instance of the class WitnessResponseListener.
