This is my first time coding using this library and looking at the documentation i could able to create a wallet.

Now I am trying to send some coins in test3network, how do load my wallet with some coins programmatically?

use testnet faucet to send test bitcoin to your wallet address. link: https://testnet.manu.backend.hamburg/faucet.

Use  below code to load wallet file and get balance:

File file = new File("195da336-a311-4f69-8707-fcfb5f61dd5a.dat");
 Wallet wallet = Wallet.loadFromFile(file);
        System.out.println(wallet.getBalance().toFriendlyString());
 
        // Set up the components and link them together.
 final NetworkParameters params = TestNet3Params.get();
 BlockStore blockStore = new MemoryBlockStore(params);
 BlockChain chain = new BlockChain(params, wallet, blockStore);


 final PeerGroup peerGroup = new PeerGroup(params, chain);
 peerGroup.setFastCatchupTimeSecs(wallet.getEarliestKeyCreationTime());
 peerGroup.startAsync();
 // Now download and process the block chain.
 peerGroup.downloadBlockChain();
        peerGroup.stopAsync();
        wallet.saveToFile(file);
       
        System.out.println("Synchronization completed");
        System.out.println(wallet.getBalance().toFriendlyString());

Thanks ajit,

I am trying to create a new Wallet by giving something like:

Wallet wallet = new Wallet(params);

wallet.autosaveToFile(new File("app.wallet"), 1000, TimeUnit.MILLISECONDS,null);
peerGrp.addWallet(wallet);

If i create a new wallet how do i initialize the balance instead of using the existing ones?

Try this one to create wallet :

public class WalletCreation {

public static void main(String[] args) throws IOException{

int bits = 128;

SecureRandom random = new SecureRandom();

DeterministicKeyChain determinstickeychain = new DeterministicKeyChain(random, bits);

DeterministicSeed seed = determinstickeychain.getSeed();

System.out.println("seed " + seed.getSeedBytes());

Wallet wallet = Wallet.fromSeed(TestNet3Params.get(), seed);

ECKey eckey = new ECKey();

wallet.importKey(eckey);

wallet.saveToFile(new File(UUID.randomUUID().toString()+".dat"));

System.out.println("Wallet has been created");

System.out.println("wallet address--->"+wallet.currentReceiveAddress());

System.out.println("wallet balance -->"+wallet.getBalance().toFriendlyString());
