import java.math.BigInteger;import java.util.Arrays;import java.util.Collections;import java.util.Checklist;
public class BookstoreContract extends Contract {
non-public static remaining String BINARY = <“Insert the compiled bytecode of the good contract right here”>
public static remaining String CONTRACT_ADDRESS = <“Insert the contract tackle right here”>
public BookstoreContract(Web3j web3j, TransactionManager transactionManager) {tremendous(BINARY, CONTRACT_ADDRESS, web3j, transactionManager);}
public static RemoteCall<BookstoreContract> deploy(Web3j web3j, TransactionManager transactionManager) {return deployRemoteCall(BookstoreContract.class, web3j, transactionManager, BigInteger.ZERO, BINARY, “”);}
public RemoteCall<TransactionReceipt> sellBook(String purchaser, String bookName, BigInteger worth) {var operate = new Operate(“sellBook”, Arrays.asList(new Tackle(purchaser), new Utf8String(bookName), new Uint256(worth)),Collections.emptyList());return executeRemoteCallTransaction(operate);}
public RemoteCall<Bool> isBookAvailable(String bookName) {var operate = new Operate(“isBookAvailable”, Collections.singletonList(new Utf8String(bookName)), Collections.singletonList(new TypeReference<Bool>() {}));return executeRemoteCallSingleValueReturn(operate, Bool.class);}}
Word: This can be a pattern code, and assumes you might be utilizing the Web3j library to work together with the Ethereum blockchain.
