这是一本学习Java语言非常好的书，适合于初学者，并具有一定深度。(This is a very good book to learn the Java language, suitable for beginners, and has a certain depth.)

主要是基于简化以后的大型电商详情页系统的背景，来重点讲解了三块内容：Redis集群架构、大型高并发缓存架构以及基于Hystrix的高可用服务架构，里边有视频地址。(Based on the background of the simplified large-scale e-commerce detail page system, this paper focuses on three parts: Redis Cluster Architecture, Large Concurrent Cache Architecture and Hystrix-based High Availability Service Architecture.)

Java Code Conventions

说明：  java 单机象棋,是一个不错的java 源代码,大家多提议见(java stand-alone chess, is a good java source code, we see more than the proposed)

Execute the StartsWith() function.

用java实现的将各种文件压缩或解压缩zip文件,不错,很好(Use a Java implementation of the various zip file, file compression or decompression is good, very good)

2.设计一个简单的课程管理系统（CourseManager）。主要功能包括： (1)课程信息的录入。主要包括：课程号（no）、课程名（name）、学分（grade）等； (2)课程信息的查询。根据课程号、课程名和学分等查询课程的信息。注意：查询结果可能不唯一。 (3)课程信息的修改。根据课程号查询到指定课程的信息，再用新的内容替换。 (4)课程信息的删除。根据课程号删除指定课程的信息。 设计时，采用层次化设计法，将类分为界面层（ui）、功能层（business）和持久层（persistence）3层，放在不同子包中。整个系统的代码放在exe4_2包中。(2. Design a simple course management system (CourseManager). Key features include: (1) entry program information. Including: course number (no), course name (name), credits (grade) and the like (2) information about courses. Information based curriculum, course name and credit and other inquiries courses.

Remove a specified course of information based curriculum. Design, the use of hierarchical design method, the class is divided into the interface layer (ui), the functional layer (business) and persistence (persistence) 3 layers in different sub-packages.
