Query Ledger Data
In this section, we will guide you through the steps of querying your account balance, enabling you to retrieve the most current information about the available funds in your new Hedera account.
Note: You can always check the "Code Check ✅ " section at the bottom of each page to view the entire code if you run into issues. You can also post your issue to the respective SDK channel in our Discord community here or on the GitHub repository here.
You can request the cost of a query prior to submitting the query to the Hedera network. Checking an account balance is free of charge today. You can verify that by the method below.
Java
JavaScript
Go
//Request the cost of the query
Hbar queryCost = new AccountBalanceQuery()
.setAccountId(newAccountId)
.getCost(client);
System.out.println("The cost of this query is: " +queryCost);
//Request the cost of the query
const queryCost = await new AccountBalanceQuery()
.setAccountId(newAccountId)
.getCost(client);
console.log("The cost of query is: " +queryCost);
//Create the query that you want to submit
balanceQuery := hedera.NewAccountBalanceQuery().
SetAccountID(newAccountId)
//Get the cost of the query
cost, err := balanceQuery.GetCost(client)
if err != nil {
panic(err)
}
println("The account balance query cost is:", cost.String())
You will verify the account balance was updated for the new account by requesting a get account balance query. The current account balance should be the sum of the initial balance (1,000 tinybars) plus the transfer amount (1,000 tinybars) and equal to 2,000 tinybars.
Java
JavaScript
Go
//Check the new account's balance
AccountBalance accountBalanceNew = new AccountBalanceQuery()
.setAccountId(newAccountId)
.execute(client);
System.out.println("The account balance after the transfer: " +accountBalanceNew.hbars);
//Check the new account's balance
const getNewBalance = await new AccountBalanceQuery()
.setAccountId(newAccountId)
.execute(client);
console.log("The account balance after the transfer is: " +getNewBalance.hbars.toTinybars() +" tinybar.")
//Check the new account's balance
newAccountBalancequery := hedera.NewAccountBalanceQuery().
SetAccountID(newAccountId)
//Sign with client operator private key and submit the query to a Hedera network
newAccountBalance, err := newAccountBalancequery.Execute(client)
if err != nil {
panic(err)
}
//Print the balance of tinybars
fmt.Println("The hbar account balance for this account is", newAccountBalance.Hbars.AsTinybar())
Congratulations! You have successfully transferred HBAR to another account on the Hedera Testnet! If you have followed the tutorial from the beginning, you have completed the following thus far:
⭐
- Set up your Hedera environment to submit transactions and queries.
- Created an account.
- Transferred HBAR to another account.
