This the balance of Ether in that contract in wei. You may want to convert this to Ether. If 1 Ether equals 10¹⁸ wei, simply move the decimal eighteen places to the left. Voila! Now we know there’s a balance of 115845.353546137586475837 Ether in TheDAO Withdraw contract.

When we run the application, many things are already done. Getting back to our web3j client extension, at build time, we want to declare the Web3j service to be exposed and also to be able to configure this service at runtime, so I can choose what configuration to use without needing to compile the whole app. The account from which I want to transfer some ether has a balance of 10000 ether.

It's worth noting that, as stated in the official documentation (https://web3j. readthedocs.io/en/latest/smart_contracts.html), transactional calls do not return any values, regardless of the return type specified on the method. Sending Ether Web3j web3 = Web3j.build(new HttpService()); Credentials credentials = WalletUtils.loadCredentials("password", "/path/to/walletfile"); TransactionReceipt transactionReceipt = Transfer.sendFunds(web3, credentials, “0x", BigDecimal.valueOf(0.2), Convert.Unit.ETHER).send(); 6/28/2017 Wei is the smallest unit of Ether, and a Gwei consists of a billion wei.

web3j is a lightweight, reactive Java and Android library for integrating applications with Ethereum blockchains After constantly using a calculator to convert between Ether units i thought it would be a good idea to implement the EthereumJS-Units Project on a website for easy accesability. For clarity reasons there is a simple and full converter page, since the majority wouldn't bother for any other units than Ether, Gwei and Wei. A Transaction Manager in Web3j is an abstraction that controls how transactions are signed and broadcast to the Ethereum network, via a connected client. You can pass an implementation to a smart contract wrapper when deploying or loading a contract, or you can use it to directly send transactions in a more manual way. The balance is stored by default in the smallest denomination of ether called wei (1 ether = 10^18 wei) but Web3j provides a convenience utility class Convert to convert values between different units.

You may check out the related API usage on the sidebar. If you are attempting to do this in web3j, you would use org.web3j.utils.toWei (valueInEther, Unit.ETHER); where valueInEther is a String or BigDecimal. To expand on the answer, you wouldn't typically send ether to your smart contract as a parameter to obtainTok (). The account from which I want to transfer some ether has a balance of 10000 ether.
