A pattern sensible contract:
Right here’s an instance of a easy sensible contract for the Enchanted Bookstore situation that we used within the earlier put up, carried out in Java utilizing the Ethereum sensible contract language, Solidity:
import org.web3j.abi.datatypes.Deal with;import org.web3j.abi.datatypes.Bool;import org.web3j.abi.datatypes.Operate;import org.web3j.abi.datatypes.Kind;import org.web3j.abi.datatypes.Utf8String;import org.web3j.abi.datatypes.generated.Uint256;import org.web3j.abi.TypeReference;import org.web3j.protocol.Web3j;import org.web3j.protocol.core.RemoteCall;import org.web3j.protocol.core.strategies.response.TransactionReceipt;import org.web3j.tx.Contract;import org.web3j.tx.TransactionManager;
import java.math.BigInteger;import java.util.Arrays;import java.util.Collections;import java.util.Record;
public class BookstoreContract extends Contract {
non-public static closing String BINARY = <“Insert the compiled bytecode of the sensible contract right here”>
public static closing String CONTRACT_ADDRESS = <“Insert the contract deal with 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 value) {var perform = new Operate(“sellBook”, Arrays.asList(new Deal with(purchaser), new Utf8String(bookName), new Uint256(value)),Collections.emptyList());return executeRemoteCallTransaction(perform);}
public RemoteCall<Bool> isBookAvailable(String bookName) {var perform = new Operate(“isBookAvailable”, Collections.singletonList(new Utf8String(bookName)), Collections.singletonList(new TypeReference<Bool>() {}));return executeRemoteCallSingleValueReturn(perform, Bool.class);}}
Observe: This can be a pattern code, and assumes you’re utilizing the Web3j library to work together with the Ethereum blockchain. Additionally, you will want to interchange the `BINARY` fixed with the compiled bytecode of your sensible contract and the `CONTRACT_ADDRESS` with the precise deal with of your deployed contract.
This sensible contract permits the bookstore to promote books and test if a selected guide is offered. The `sellBook` perform takes within the purchaser’s deal with, the guide title, and the value as parameters and information the sale transaction. The `isBookAvailable` perform checks if a given guide is at present out there for buy.
