对类的创建

试编程完成创建一个名为"BankAccount”的类，包含以下私有属性和公有方法属性: 帐户名 (accountNumber),帐余额 (balance)方法: 存款方法(deposit),取款方法(withdraw),获取账户余额getBalance()，获取帐户名称 getAccountNumber()

public class BankAccount {
    private String accountNumber;
    private double balance;

    public BankAccount(String accountNumber, double balance) {
        this.accountNumber = accountNumber;
        this.balance = balance;
    }

    public void deposit(double amount) {
        balance += amount;
    }

    public void withdraw(double amount) {
        if (balance >= amount) {
            balance -= amount;
        } else {
            System.out.println("Insufficient funds");
        }
    }

    public double getBalance() {
        return balance;
    }

    public String getAccountNumber() {
        return accountNumber;
    }
}
