Whenever you add source code to your classes, you'll be able to test it with:
```
$ mvn package
$ mvn compile

You can also execute with `exec:java`

You can look up addresses on your wallet by passing the address as an argument to `getAddressInfo`:
```java
public AddressInfo getAddressInfo(String address) throws GenericRpcException {
return new AddressInfoMapWrapper((Map<String, ?>) query("getaddressinfo", address));
}
String addr1 = "mvLyH7Rs45c16FG2dfV7uuTKV6pL92kWxo";
AddressInfo addr1Info = rpcClient.getAddressInfo(addr1);
System.out.println("Address: " + addr1Info.address());
System.out.println("MasterFingerPrint: " + addr1Info.hdMasterFingerprint
());
System.out.println("HdKeyPath: " + addr1Info.hdKeyPath());
System.out.println("PubKey: " + addr1Info.pubKey());
```
The output will look something like this:
```
Address: mvLyH7Rs45c16FG2dfV7uuTKV6pL92kWxo

### Running Your Code
The code for these examples can be found in [the src directory](src/17_2_App-getinfo.java) and should be installed into the standard directory structure created here as `~/java-project/src/main/java/com/blockchaincommons/lbtc/App.java`. It can then be compiled and run.
```
$ mvn compile
$ mvn exec:java -Dexec.mainClass=com.blockchaincommons.lbtc.App
