问题描述：编写一个JAVA程序，用面向对象设计的方法编写一个电话卡的类。包括卡号、密码、余额、拨入号码等 b）基本要求：类的属性有卡号、密码、余额、拨入号码，电话卡的常用操作可以用连接电话方法、返回余额方法与通电话方法来实现。 c）方法功能描述： 构造方法（PhoneCard(卡号,密码,余额,拨入号码)）可以完成属性值初始化赋值，并判断余额，余额为负就退出系统，请在构造方法中将初始时的连接置为false即表示没有连接。 卡号long cardNumber 密码private int password,余额double balance,拨入号码string connectNumber boolean connected(一个布尔类型变量表示电话卡连接状态，初始时默认没有连接，值为false，当调用连接电话方法()后，在判断卡号和密码相匹配后值置为true) 连接电话方法(performConnection(卡号,密码))可以完成检查卡号和密码，它是只有在卡号和密码相匹配时才连接 返回余额方法(getBalance())得到电话卡的余额 通电话方法(performDial())是模拟通过过程中，余额会不断减少，每调用此方法，电话卡的余额减少0。5元,打一次电话调用一次

linux filesystem bootdisk-howto.This document describes how to design and build boot/root diskettes for Linux. These disks can be used as rescue disks or to test new system components. You should be reasonably familiar with system administration tasks before attempting to build a bootdisk. If you just want a rescue disk to have for emergencies,

This is the library for all storage drivers. It simplifies writing a storage driver by implementing 90 percent of the code required to support Plug and Play, Power Management, et cetera. This library is used by disk.sys, cdrom.sys and the tape class drivers. No INF file is needed to install this library. The library is 64-bit compliant.

The sfloppy sample is a super floppy driver that resides in the directory \\Ntddk\Src\Storage\sfloppy. It is a class driver for Super Floppy disk drives. It sits a level above the port driver (ATAPI, USB, etc) in the driver stack, and brokers communication between the application level and the port driver. The floppy driver takes requests from filesystem drivers and then sends the appropriate SCSI_REQUEST_BLOCK (SRB) to the port driver. It is compatible with x86 and IA64 platforms.

This library allows creating, modifying and extracting zip archives in the compatible way with PKZIP (2.5 and higher) and WinZip. Supported are all possible operations on the zip archive: creating, extracting, adding, deleting files from the archive, modifications of the existing archive. There is also the support for creating and extracting multiple disk archives (on non-removable devices as well) and for password encryption and decryption. This module uses compression and decompression functions from zlib library by Jean-loup Gailly and Mark Adler.

DataBurn is an Objective-C example which demonstrates some of the features of DRTracks. The sample illustrates how to create a DRFolder from an existing folder on the source disk and burn it to disc, creating a hybrid ISO9660/Joliet/HFS+ data CD. The sample also uses the DiscRecordingUI framework to present the standard burn setup and progress user interfaces.
