本书由浅入深、循序渐进地介绍了Java语言的发展、编程环境、开发工具、基本语法、面向对象编程、异常处理、线程、输入输出流、GUI编程、网络编程、数据库编程等内容,并结合大量的实例进行讲解。本书内容注重理论与实践结合,参考了Java在线官方文档及国内外优秀的Java程序设计教材的知识体系内容。针对中国学生英文水平及实
There really is no point in creating a single threaded OpenCL application. The individual stream processors are too slow. If you are only using one stream processor, then it is very likely not worth the overhead of sending data to the stream processor to process. Now that we have ...

After completing this chapter, you will be able to draw strings, images, and shapes via the Graphics class in your Java programs. We discuss geometry-related classes—Polygon, Rectangle, Point, and Dimension, and the Shape interface—you will see these throughout the remaining AWT objects. You...
目前分布式链路追踪系统基本都是根据谷歌的《Dapper 大规模分布式系统的跟踪系统》这篇论文发展而来,主流的有 Pinpoint,Skywalking,CAT(当然也有其他的例如 Zipkin,Jaeger 等产品,不过总体来说不如前面选取的 3 个完成度高)等。 Zipkin 是Twitter 公司开源的一个分布式链路追踪工具,Spring Cloud Sleuth 实际是基于 Zipk...

In comparison with the default single-threaded collector, the break-even point for the parallel collector appears to be somewhere between two and four CPUs, depending on the platform and the application. This is expected to further improve in future releases. ...
The Java linker creates a runnable program from compiled classes. See also compiler, interpreter, runtime system. literal The basic representation of any integer, floating point, or character value. For example, 3.0 is a double-precision floating point literal, and "a" is a character literal. ...
Unit testing tools like JUnit and TestNg come into play at this point. These frameworks help you write automated tests faster, with a simple syntax and rapid feedback on passed tests. JUnit emphasizes the philosophy of “testing first,” which boosts the programmer’s productivity and the code...
