求助

我是个新手写了这么一个程序：我的运行结果是这样的run：
                        CUSTOMERS REPORT
                        ================Customer: Simms, Jane
Savings Account:current balance is￥500.00
Checking Account:current balance is￥200.00Customer: Bryant, Owen
Checking Account:current balance is￥200.00Customer: Soley, Tim
Savings Account:current balance is￥1,500.00
Checking Account:current balance is￥200.00Customer: Soley, Maria
Savings Account:current balance is￥150.00
成功生成（总时间：0 秒）
但最后一个人Soley, Maria少了一个Checking Account:current balance is $ 200.00我不知道是什么原因看不出哪有漏洞
希望能给点建议谢谢下面的这才是正确答案对于钱的符号不做要求CUSTOMERS REPORT
