编写程序计算三门课的平均成绩，要求应用程序分别用Java语言三种不同的循环语句实现，每门课的成绩用Math类的random()方法随机产生（random()产生的数值在0和1之间），成绩范围为40~100。 提示:自定义一个类，该类实现一个返回随机数的函数。在main函数里测试时直接调用该类的获取随机数方法。 获得随机数相关的类为:java.lang.Math 需要时可引入该类即:import java.lang.Math -Write a program grade point average calculation of three lessons to require the application were used Java language in three different loop realization of the achievements of each course with the Math class, random () method of randomly generated (random () produces values between 0 and between 1), results range from 40 ~ 100. Tip: Customize a class that implements a function to return random numbers. In the main function, where the test is called the class to obtain a direct method of random numbers. Obtain a random number associated category: java.lang.Math necessary for the introduction of the class that is: import java.lang.Math

应用背景MP3播放器开发源码及电路图,使用AT89C51SNDIC-R0开发，有原理图和源代码，这款MP3播放器以at89c51snd1c为核心，以硬盘为存储介质，液晶屏为双行显示，每行显示7.5个汉字，这块液晶屏以ST7920作为主控制器，内部集成8129个汉字，液晶屏在这个播放器中用来显示歌曲名称以及一些播放状态。关键技术1)MCS51内核，可以利用单片及开发软件Keil软件方便开发mp3播放器，无需特殊软件平台；     2)MPEG I/II-Layer 3 hardware decoder       .独立MP3 Decoder      .支持48,44.1,32,24,22.05,16khz取样频率      .支持软件31阶音量控制,高中低音均衡控制      .重低音效果     3)集成DAC部件，支持PCM,IIS格式；     4)64K字节片上代码存储空间（100K次擦写寿命）     5)4K字节boot flash memory,USB/UART下载代码     6)集成USB1.1 device部件     7)MMC卡接口     8)IDE/ATAPI接口（HDD/CD-ROM Interface)     9)2通道ADC,8Khz取样     .......................    关于该芯片的具体信息，可以访问www.atmel.com获取at89c51snd1c的datasheet.    这款MP3播放器以at89c51snd1c为核心，以

Anthill是一个确保受控建造过程和促进在组织内部共享知识的工具。Anthill在每一次建造之前从项目最新版本的源文件库中借出文件，并在每一次建造之后用一个唯一的版本号标记源文件库。它支持的库适配器有：CVS (Concurrent Versions System), Visual Source Safe, Perforce, PVCS, StarTeam, MKSIntegrity, 和 FileSystem. 来源：http://freshmeat.net/projects/ant8/?topic_id=45%2C822%2C52%2C46%2C861 -Anthill is guarantees is controlled the construction process and the promotion in the organization interior sharing knowledge tool. Anthill before each construction loans the document from in the project newest edition source document storehouse, and after each construction marks the source document storehouse with an only edition number. It supports the storehouse adapter includes: CVS (Concurrent Versions System), Visual Source Safe, Perforce, PVCS, StarTeam, MKSIntegrity, with FileSystem. origin: Http://freshmeat.net/projects/ant8/?
