“YOUR_SUPER_SECURE_PASSWORD”,
“YOUR_API_CODE”);

10. System.out.println(wallet.getIdentifier());
Wallet wallet = new Wallet(
“http://localhost:8080/”,
“YOU_API_CODE”,
“YOUR_GUID”,
“YOUR_SUPER_SECURE_PASSWORD”);

11. // get an address from your wallet and include only transactions with up to 3
// confirmations in the balance
Address addr = wallet.getAddress(“1JzSZFs2DQke2B3S4pBxaNaMzzVZaG4Cqh”, 3);
System.out.println(String.format(“The balance is %s”, addr.getBalance()));
// send 0.2 bitcoins with a custom fee of 0.01 BTC and a note
// public notes require a minimum transaction size of 0.005 BTC
PaymentResponse payment = wallet.send(“1dice6YgEVBf88erBFra9BHf6ZMoyvG88”,
20000000L, null, 1000000L);

12. System.out.println(String.format(“The
payment TX hash is %s”,
