Examples with FileInfoQuery com.hedera.hashgraph.sdk.FileInfoQuery used on opensource projects

Example 1 with FileInfoQuery

use of com.hedera.hashgraph.sdk.FileInfoQuery in project hedera-sdk-java by hashgraph.

the class DeleteFileExample method main.

public static void main(String[] args) throws PrecheckStatusException, TimeoutException, ReceiptStatusException {
    Client client = Client.forName(HEDERA_NETWORK);
    // Defaults the operator account ID and key such that all generated transactions will be paid for
    // by this account and be signed by this key
    client.setOperator(OPERATOR_ID, OPERATOR_KEY);
    // The file is required to be a byte array,
    // you can easily use the bytes of a file instead.
    String fileContents = "Hedera hashgraph is great!";
    TransactionResponse transactionResponse = new FileCreateTransaction().setKeys(OPERATOR_KEY).setContents(fileContents).setMaxTransactionFee(new Hbar(2)).execute(client);
    TransactionReceipt receipt = transactionResponse.getReceipt(client);
    FileId newFileId = Objects.requireNonNull(receipt.fileId);
    System.out.println("file: " + newFileId);
    // now delete the file
    TransactionResponse fileDeleteTransactionResponse = new FileDeleteTransaction().setFileId(newFileId).execute(client);
    // if this doesn't throw then the transaction was a success
    fileDeleteTransactionResponse.getReceipt(client);
    System.out.println("File deleted successfully.");
    new FileInfoQuery().setFileId(newFileId).execute(client);
// note the above fileInfo will fail with FILE_DELETED due to a known issue on Hedera
