[Ethereum] Convert ethereum balance getting in biginteger to ether

etherweb3j

public BigInteger getBalance(String address) 
{
    /*Web3j web3j  */

   createEthreumConnection();
   EthGetBalance ethGetBalance = null;
   try {
      ethGetBalance = web.ethGetBalance(address, DefaultBlockParameterName.LATEST).sendAsync().get();
   } catch (InterruptedException e) {               
      logger.error("Interrupted Exception "+e);
   } catch (ExecutionException e) {         
      logger.error("ExecutionException Exception "+e);
   }
   return ethGetBalance.getBalance();
}

I am using the above code for getting the ethereum balance but the balance fetched in given format 4555500000 , I want to be shown as Ethereum balance.For example Bitcoin j provides MonetaryFormat.BTC.noCode().format(addressBalance)

@Luiz Soares Thank you for giving me the clue of the value being in WEI but solution provided didn't worked me.After some digging the documentation again got the solution

Convert.fromWei(ethGetBalance.getBalance().toString(), Unit.ETHER);

[Ethereum] How to create accounts and also retrieving the ether balance with web3j in a java file

The "ethGetBalance" method will return the balance of any given account. Pls see example below:

// connect to node
Web3j web3 = Web3j.build(new HttpService());  // defaults to http://localhost:8545/

// send asynchronous requests to get balance
EthGetBalance ethGetBalance = web3
  .ethGetBalance("0xAccountAddress", DefaultBlockParameterName.LATEST)
  .sendAsync()
  .get();

BigInteger wei = ethGetBalance.getBalance();

[Ethereum] How to view custom token balance in ether wallet using web3

Here is my suggestions:

ERC20 token balance

Just to clarify, all ERC20 tokens have the same set of methods (ERC20 protocol). Now, there are two ways to accomplish your task:

use ERC20 balanceOf(address _owner) method

// Get the account balance of another account with address _owner

function balanceOf(address _owner) public constant returns (uint256 balance);

Example: first, create token instance

var tokenInst = web3.eth.contract(tokenABI).at(tokenAddress);

Then you can call methods of the token. For balance you should write the following:

tokenInst.balanceOf.call(address_to_check)

use balances map if it is public.

// Balances for each account

mapping (address => uint256) balances;

Example is similar to previous: first, create token instance

var tokenInst = web3.eth.contract(tokenABI).at(tokenAddress);

Then you can call methods of the token. For balance you can also write the following:

tokenInst. balances.call(address_to_check)

ETH balance

You want to use web3 balanceOf() method.

Example: web3.eth.getBalance(address);
