#Sample use
##Very simple funds transfer
This is a simple transfer operation of 1 BTS from account **bilthon-15** to **bilthon-5**
```java
// 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.
```java
// 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```.
