Java's Open-Source ecosystem is powerful and healthy, which is one of the main reasons why we (Oreilly) created OSCON Java (Open Source Convention Java. Over the past 10 years, some projects have been widely accepted and have dominated the Java software development world, and some have even affected users' daily lives.

form, a few points can be seen. Although the post-compilation actions are self-building, VS does not introduce this concept, I directly see what I want to use. Unconsciously. "This is the initiative to build their own ah." "VS also supports copying non-code files to the compiled folder after compilation.In my example, both reader and viewer are connected to the database, and I want to put the connection string in a file, such as Connection.txt, with two programs in the sibling folder.Because of

frameworks, libraries, and software collections. If you are not sure how you should choose a specific plan, be sure to refer to this list, which even divides the entries by category.It also includes some of the old tools that are still in use, including frameworks that simplify mapping, tools to build application cycles and dependencies, libraries that handle bytecode programming, and so on.Concluding remarksThis is, of course, just the tip of the ic

Scala is an object-oriented language running on Java JVM. It supports function programming and is more flexible in syntax than Java. At the same time, through the Akka library, Scala supports powerful Actor-based multi-thread programming. With these advantages, I recently wanted to use Scala in a new project, but in th

General programming is mostly used to store configuration information. for JDBC, you can write the database connection string to xml. to modify the data source, you only need to modify the xml. you do not need to re-compile the java file, these configuration information is put together. When someone else reads the code you write, it makes it easier for many java

Essay background: In a lot of times, many of the early friends will ask me: I am from other languages transferred to the development of the program, there are some basic information to learn from us, your frame feel too big, I hope to have a gradual tutorial or video to learn just fine. For learning difficulties do not know how to improve themselves can be added: 1225462853 to communicate to get help, access to learning materials.cp2044-in-depth Java

The importance of the HTTP protocol I don't need to say much, httpclient. Compared to the traditional JDK urlconnection, it adds ease of use and flexibility (specifically, we'll discuss later), not only is it easier for clients to send HTTP requests, It also facilitates the developer testing interface (based on HTTP protocol), which improves the efficiency of the development and facilitates the robustness of the code. Therefore, the mastery of httpclient is very important compulsory content, Mas

Several methods and examples for connecting to databases in Java projects1. The most primitive writing method (also for Beginners)First import the database to connect to the basic class, and then the other is simple. In actual operation, you only need to load the driver class and then call the SQL statement. The following is a simple program example.// Select. javaImport java.net. URL;Import java. SQL .*;Cl

So, if you want to be truly proficient in Java technology, you also need your own efforts and sweat. After all, the coffee smells fragrant, but itself is bitter, only do not abandon this bitter, can taste the real taste. But you don't have to consider this s
