java 练习题

1、编写程序，模拟银行账户功能。要求如下、
属性、账号、储户姓名、地址、存款余额、最小余额。
方法、存款、取款、查询。根据用户操作显示储户相关信息。如存款操作后，显示储户原有余额、

今日存款数额及最终存款余额；取款时，若最后余额小于最小余额，拒绝收款，并显示“至少保留余额XXX”

public class TestBank {


public static void main(String[] args) {


function();
}


private static void function() {
Scanner s = new Scanner(System.in);
Bank b = new Bank();
cc: while (true) {
System.out.println("请对你的账户进行操作:存款-->1,取款-->2,查询-->3");

w: while (console > 0) {
