求大神帮忙改程序

Question

不知道楼主想要什么样的结构，帮楼主调整了一点代码，剩下的楼主自己完善吧。    public static void main(String[] args) {
        Account A=new Account();  
        Scanner reader=new Scanner(System.in);
        System.out.println("请输入账号：");
        A.number=reader.next();
        int index = 0;
        while(!A.number.equals("10010")){
            index ++;
            if (index == 3) {
                System.out.println("对不起，您输入的错误次数超过三次，系统自动退出");
                System.exit(0);
            }
            System.out.println("账号输入错误!,請重新輸入\n请输入账号");
            A.number=reader.next();
        }
//       if(A.number.equals("10010")){
            System.out.println("查询余额请按1；取款请按2；存款请按3");
            m=reader.nextInt();
//            if(m<0||m>3) {
//                System.out.println("操作错误！");
//            }
            while (m<0 || m>3) {
                System.out.println("操作错误！\n请重新输入");
                System.out.println("查询余额请按1；取款请按2；存款请按3");
                m=reader.nextInt();
            }
            
            if(m==1) {
                System.out.println("您当前余额为："+A.CheckBalance());
            }
            else if(m==2) {
                System.out.println("请输入要取出的金额：");
                int money2=reader.nextInt();
                if(money2>A.balance) {
                    System.out.println("余额不足！");
                }
                else {
                    A.Withdrawing(money2);
                    System.out.println("取款后余额为："+A.CheckBalance());
                    System.out.println("要继续 取款吗（Y/N）?");
                    p=reader.next();

Answer 1

上面的代码错误三次就会自动退出了，楼主可以按照上面的思路进行修改。
楼主刚开始的代码全是if else，基本上都是直入直出的，想循环操作，换为while，然后进行下代码调整。

Answer 2

调整了一个改进版，对于输入没有做校验，仅供参考    public static void main(String[] args) {
        Account A=new Account();  
        Scanner reader=new Scanner(System.in);
        System.out.println("请输入账号：");
        A.number=reader.next();
        int index = 0;
        while(!A.number.equals("10010")){
            index ++;
            if (index == 3) {
                System.out.println("对不起，您输入的错误次数超过三次，系统自动退出");
                System.exit(0);
            }
            System.out.println("账号输入错误!,請重新輸入\n请输入账号");
            A.number=reader.next();
        }
        System.out.println("查询余额请按1；取款请按2；存款请按3");
        m=reader.nextInt();
        
        while (m<0 || m>3) {
            System.out.println("操作错误！\n请重新输入");
            System.out.println("查询余额请按1；取款请按2；存款请按3");
            m=reader.nextInt();
        }
        
        // 查询余额
        if(m==1) {
            System.out.println("您当前余额为："+A.CheckBalance());
        }
        // 取款
        else if (m==2) {
            boolean isGoOn = true;
            while(isGoOn) {
                System.out.println("请输入要取出的金额：");
                int money2=reader.nextInt();
                if(money2>A.balance) {
                    System.out.println("余额不足！");
                }
                while (money2 <= A.balance) {
                    A.Withdrawing(money2);
                    System.out.println("取款后余额为："+A.CheckBalance());
                    System.out.println("要继续 取款吗（Y/N）?");
                    p=reader.next();
                    if (p.equalsIgnoreCase("Y")) {
                        isGoOn = true;
                        // 仅作跳出while循环用，无实际意义
                        money2 = A.balance + 1; 
                    } else {
                        System.exit(0);
                    }
                }
            }
        }
        // 存款
        else if(m==3) {
            boolean isGoOn = true;
            while(isGoOn) {
                System.out.println("请输入要存入的金额：");
                int money1=reader.nextInt();
                A.deposit(money1);
                System.out.println("存款后余额为："+A.CheckBalance());
                System.out.println("要继续 存款吗（Y/N）?");
                s=reader.next();
                if (s.equalsIgnoreCase("Y")) {
                    isGoOn = true;
                } else {
                    System.exit(0);
                }
            }
        }
    }

Answer 3

               if (s.equalsIgnoreCase("Y")) {
                    isGoOn = true;
                } else {
                    System.exit(0);
                }这里的if 直接判断N的情况就可以了，因为isGoOn本身就是true
如果是N直接退出就可以了，否则会继续循环下去，剩下的你自己调吧
今天加班，事情做完了顺便把你这段代码拿出来调了调
