Original intention and arrangement descriptionJava high concurrent Kill system API is a Java project from the online tutorial, and I am the first project to touch Java. Originally a C # code farm, the company plans to part of the business to Java, so I use business time to self-study

package in documentation, in a more comprehensible language, and in a well-organized way. So same, if you have enough power to learn Java libraries directly through documentation, then basically you don't need to look at other books. In addition, documentation is also a prerequisite for programming manuals, my desktop has three documentation shortcuts, The documentation of the documentation and j2sdkee1.3.

Ibm®websphere®application Server V7 delivers enhancements to its java™persistence API (JPA), supports optimization of data access to IBM®DB2 data servers to improve security, and has significant data-reduction visits Ask for the potential of overhead. The way to achieve optimization is to support static SQL access by using the built-in integration of WebSphere JPA with the IBM Data Studio pureQuery Runtime-

recommended that you first understand a set of frameworks, do not drill into a certain aspect of the knowledge point, such as you can first through the spring mvc+hibernate (or even Jsp+servlet+javabean) to build a basic front-end page +MVC architecture + Background code + data for Web small projects (such as student management systems), first understand the web framework based on the development of a complete set of knowledge system, and then continue to understand the Web components of the

, there will be grammatical and semantic errors, but in the subsequent learning will gradually become proficient. and mastering good English reading ability is the necessary ability to learn and communicate cutting-edge technology.3. Focus on the exercise of reading ability and understanding of the working mechanism, a language is often profound, knowledge points are difficult to master, it is almost impossible to remember all the functions, not to me

In Java programming, some knowledge cannot be learned only through language specifications or standard API documentation. In this article, I'll try to collect some of the most common idioms, especially those that are hard to guess. (Joshua Bloch's "effective Java" gives a more detailed account of this topic, and can learn
