用java实现声明银行账户类Account，成员变量包括账号、储户姓名、开户时间、身份证号码、存 款余额等账户信息，成员方法包括开户、存款、取款、查询(余额、明细)、销户等操作

以下是用Java实现声明银行账户类Account的代码：

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class Account {
    private String accountNumber;
    private String accountHolderName;
    private Date accountOpeningDate;
    private String idNumber;
    private double balance;
    private List<String> transactionHistory;

    public Account(String accountNumber, String accountHolderName, String idNumber) {
        this.accountNumber = accountNumber;
        this.accountHolderName = accountHolderName;
        this.idNumber = idNumber;
        this.accountOpeningDate = new Date();
        this.balance = 0;
        this.transactionHistory = new ArrayList<>();
    }

    public void deposit(double amount) {
        if (amount > 0) {
            this.balance += amount;
            String transaction = "Deposit: +" + amount + ", Balance: " + this.balance;
            this.transactionHistory.add(transaction);
            System.out.println("Deposit successful!");
        } else {
            System.out.println("Invalid deposit amount!");
        }
    }

    public void withdraw(double amount) {
        if (amount > 0 && amount <= this.balance) {
            this.balance -= amount;
            String transaction = "Withdrawal: -" + amount + ", Balance: " + this.balance;
            this.transactionHistory.add(transaction);
            System.out.println("Withdrawal successful!");
        } else {
            System.out.println("Invalid withdrawal amount or insufficient funds!");
        }
    }

    public void checkBalance() {
        System.out.println("Current balance: " + this.balance);
    }

    public void transactionHistory() {
        for (String transaction : this.transactionHistory) {
            System.out.println(transaction);
        }
    }

    public void closeAccount() {
        this.balance = 0;
        this.transactionHistory.clear();
        System.out.println("Account closed successfully!");
    }

    public String getAccountNumber() {
        return accountNumber;
    }

    public String getAccountHolderName() {
        return accountHolderName;
    }

    public Date getAccountOpeningDate() {
        return accountOpeningDate;
    }

    public String getIdNumber() {
        return idNumber;
    }
}

在这个类中，我们定义了五个成员变量：账号、储户姓名、开户时间、身份证号码、存款余额和交易历史。在我们创建一个新的账户时，账号和储户姓名是必须的，开户时间会自动设置为当前时间，存款余额会初始化为0，交易历史会初始化为空列表。我们还定义了五个成员方法：存款、取款、查询余额、查询交易历史和销户。在存款和取款操作中，我们检查金额是否合法，如果合法则更新余额和交易历史。在查询余额和查询交易历史操作中，我们简单地打印出相应的信息。在销户操作中，我们清除余额和交易历史。

这是一个简单的银行账户类的实现，可以根据需要进行扩展和修改。
