用Java创建一个银行取钱的代码，要求代码不能过短

以下是一个简单的Java代码示例，用于银行取钱：

import java.util.Scanner;

public class Bank {

    private double balance;

    public Bank(double initialBalance) {
        balance = initialBalance;
    }

    public void withdraw(double amount) {
        if (amount > balance) {
            System.out.println("Insufficient funds.");
        } else {
            balance -= amount;
            System.out.println("$" + amount + " has been withdrawn from your account.");
        }
    }

    public double getBalance() {
        return balance;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your initial balance:");
        double initialBalance = scanner.nextDouble();
        Bank bank = new Bank(initialBalance);
        System.out.println("Your current balance is $" + bank.getBalance());
        System.out.println("Enter the amount you wish to withdraw:");
        double amount = scanner.nextDouble();
        bank.withdraw(amount);
        System.out.println("Your new balance is $" + bank.getBalance());
    }
}

该代码创建了一个Bank类，其中包含了一个存款余额变量和一个取款方法。在main方法中，创建了一个Bank对象，并让用户输入初始余额和要取款的金额。然后，调用Bank对象的withdraw方法进行取款，并打印出新的余额。

注意：此代码是一个简单的示例，实际的银行系统应该包含更多的安全措施和验证。
