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

翻译 maninwest@Codeforge 作者:Sergey Nozhenko@CodeProject介绍：CoStream 是的 PipeStream 无缓存替代选择。背景在生产者/消费者模式下，如果我们知道一个消费者确定要读取stream 读到结束或者如果不能读到结束就处理，那么同步stream 就不需要维护自己的内部缓存，完全依赖于 Read 方法调用者的缓存。在Read 方法中，CoStream 保存到目标缓存的引用并等待，直至完成。而 write 方法从源缓存中复制数据到目标缓存，会给读取者发送信号缓存已准备就绪或者需要等待期 Read 调用（如果来源缓存中有未消耗的数据剩下或者返回到Writer 调用者）。使用代码CoStream 不能在单个话题中使用。应该至少有两个，读取和写入话题。两者都需要关闭（或处理）stream，一边对方可以继续到结束。测试程序在  XmlDocument 中加载了一些 xml 文件。然后将其写入到 CoStream 的实例Static CoStream costream = new TestCoStream(); static string outpath; static void Main(string[] args) { // ... XmlDocument doc = new XmlDocument(); doc.Load(args[0]); outpath = args[1]; var reading_thread = new Thread(ReaderBody); reading_thread.Start(); using (var pipe = XmlWriter.Create(costream, new XmlWriterSettings { CloseOutput = true })) doc.Save(pipe); reading_thre
