说明：  编写一个程序，用以接受用户输入的两个double类型的值。一个值表示用户想要存放在银行账户中的金额。另一个值表示用户想要从银行账户中提取的金额。创建自定义异常，以确保提取的金额始终小于或等于当前的余额。引发异常时，程序应显示一则错误消息。否则，程序应显示从用户存款中扣除取款额之后的账户余额。(Write a program to accept the value of two double types that the user enters. A value represents the amount the user wants to store in a bank account. The other value is the amount that the user wants to extract from the bank account. Create a custom exception to ensure that the amount extracted is always less than or equal to the current balance. When an exception is caused, a program should display an error message. Otherwise, the program should show the balance of the account after deducting the amount from the user's deposit.)
