说明：  Java推箱子游戏（一共有50关卡，带好听的音效），完整版源码，图形界面，看上去够专业。界面和泡泡堂游戏有点相似，学习游戏编程的JAVA朋友值得一看。 (Java Sokoban game (a total of 50 points, with good sound effects), the full version of source code, graphics interface, looks professional enough. Interface and the BNB to be somewhat similar game, learning game programming JAVA friends to see.)

编写一个控制台程序，模拟在ATM机的存款和取款过程，当输入给定的卡号和密码（初始卡号和密码到数据文件里查看）时，系统能登录ATM系统，根据用户的身份不同显示不同的程序界面；取款 　　每次取款金额只能为100的倍数，总额不超过2000元，不允许透支。且取款之后，要记录取款的金额和时间。 存款 　　每次存款金额只能为100的倍数，总额不超过2000元。 修改密码 　　新密码长度不小于6位，不允许出现6位完全相同的情况，只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。(Write a console program to simulate the ATM deposits and withdrawals process, when you enter a given number and password (the initial number and password to the data file view), the system can log in ATM systems, according to the user' s identity different display different The program interface withdrawal amount each withdrawal can only be a multiple of 100, the total does not exceed 2,000 yuan, does not allow overdrafts. And withdrawals after the withdrawal of the amount to be recorded and time. Deposit Amount per Deposit only a multiple of 100, totaling no more than 2,000 yuan. Change Password New Password length not less than six, allowed six identical situation, only the old password is correct, the new password meets the requirements, and enter the same case twice before they can successfully change the password.)
