In-depth understanding of class loading mechanisms Description Before starting the text, I would like to say the purpose and benefits of writing these articles, mainly can make their own learning things to do a summary, sometimes spend a long time to learn some things, straighten out some ideas, but a few days to recall these things will become blurred, all also spend time to find relevant information, look at the information. And now do such a

and when you access the url corresponding to this file, php will automatically help you run this php script. So you can save a lot of work. For websites, everything php provides is perfect (so many companies are using it). You don't need to consider the underlying things at all. Concentrate on the application layer. When your programming experience reaches a certain level, you feel that you want to write a web server (Like apache), php cannot do it. At this time, nodejs, python,

configuration) is verbose and requires a lot of manual code (such as EJBS), so you need to be familiar with code generation tools such as Xdoclet. 22. You need to be familiar with a unit test system (JNUNIT) and learn about different build and deployment Tools (Ant,maven). 23. You need to be familiar with some of the software engineering processes that are often used in Java development. For example, Rup (rationalunifiedprocess) andagilemethodologies

almost exactly the same way as they are used directly in Build.gradle files. The only difference is that you can use the Classpath declaration with dependencies in the Buildscript code block. The Classpath declaration illustrates that class loader can use the dependencies that you provide when executing the rest of the build scripts. This is exactly what we use to Buildscript blocks of code. If you need to use the class library in your project, you need to define the dependencies code block out
