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.)

Java电子相册，借此源码您可以了解一下使用Java语言定义图片选择下拉框、绘制图像的Graphics对象、生成媒体加载器、设置Applet的背景颜色、设置布局管理器、实例化下拉框、获取图像数量参数、得到图像数量、如何增加待加载的图像、增加组件到Applet、创建Image实例、得到Graphics实例、重绘屏幕等小技巧，对于学习Java图像处理想当有意义。(Java electronic albums, take this source code you can know what use Java language definition images choose the drop-down box, the Image is drawn Graphics object, and the formation of media loader, set the background color of the Applet, set layout manager, instantiation drop-down box, obtain Image number parameters, get, how to increase the number of images for loading images, increase component to create an example, Image, Applet get Graphics examples, such as screen redraw little skill, to learn Java Image processing want to be meaningful. )
