由于篇幅原因,我无法为您提供完整的Java P2P网贷源码,我可以为您提供一个简单的Java P2P网贷系统的概述和关键代码片段,以帮助您了解其基本结构和功能。
1、我们需要创建一个表示用户的类(User):
public class User { private String name; private double balance; public User(String name, double balance) { this.name = name; this.balance = balance; } public String getName() { return name; } public double getBalance() { return balance; } public void setBalance(double balance) { this.balance = balance; } }
2、我们需要创建一个表示借贷交易的类(Transaction):
public class Transaction { private User sender; private User receiver; private double amount; public Transaction(User sender, User receiver, double amount) { this.sender = sender; this.receiver = receiver; this.amount = amount; } public User getSender() { return sender; } public User getReceiver() { return receiver; } public double getAmount() { return amount; } }
3、我们需要创建一个处理交易的类(TransactionManager):
import java.util.ArrayList; import java.util.List; public class TransactionManager { private List<Transaction> transactions; public TransactionManager() { transactions = new ArrayList<>(); } public void addTransaction(Transaction transaction) { transactions.add(transaction); transaction.getSender().setBalance(transaction.getSender().getBalance() transaction.getAmount()); transaction.getReceiver().setBalance(transaction.getReceiver().getBalance() + transaction.getAmount()); } public List<Transaction> getTransactions() { return transactions; } }
4、我们可以在主类(Main)中创建用户并执行交易:
public class Main { public static void main(String[] args) { User user1 = new User("Alice", 1000); User user2 = new User("Bob", 500); User user3 = new User("Charlie", 2000); TransactionManager transactionManager = new TransactionManager(); // Alice向Bob转账200元 Transaction transaction1 = new Transaction(user1, user2, 200); transactionManager.addTransaction(transaction1); // Bob向Charlie转账300元 Transaction transaction2 = new Transaction(user2, user3, 300); transactionManager.addTransaction(transaction2); // 输出所有交易信息 for (Transaction transaction : transactionManager.getTransactions()) { System.out.println(transaction.getSender().getName() + "向" + transaction.getReceiver().getName() + "转账" + transaction.getAmount() + "元"); } } }
这只是一个简单的Java P2P网贷系统示例,实际应用中还需要考虑更多因素,如安全性、并发性、持久化等,希望这个示例能帮助您了解P2P网贷系统的基本原理。
