Unnamed Module– When a class or JAR is loaded onto the classpath, but not the module path, it's automatically added to the unnamed module. It's a catch-all module to maintain backward compatibility with previously-written Java code. 未命名模块:当一个类或JAR被加载到classpath上,而不是模块...
Sometimes, to ensure specific platform, library, or service-provider modules in the module graph, we need to add modules to the default root set. For example, when we try to run Java 8 programs as-is with Java 9 compiler we may need to add modules. 有时候我们需要在默认根集上添加模块。

JDK is the Java Development Kit that contains all the tools and executables that are needed to develop Java programs including the execution of the Java program. In other words, JDK contains its own JRE. For now, all you need to do is download the JDK. There is one important point of ...
Running with a locally built Class Library After building the class library, you can get qbicc to use it simply by adding the command line argument--rt-version=17.alpha.0.NNN-SNAPSHOT(where NNN matches your local class lib version) to your qbicc invocation. For example, ...
The book brings answers to some commonly raised questions about Java, including how to modify the runtime behavior of a class without affecting the already tried and tested code or why Composition outweighs Inheritance. The newest edition of Head First Design Patterns is updated for Java 8. Inst...
Starting with version 0.3.0, theclasspathfunction will fall back to thejava.class.pathsystem property if the parent ClassLoader is not an instance ofURLClassLoader, which is true for Java 9 and later. Developer Information Change log
一些API会在运行期获取JAR中的资源文件(例如通过ClassLoader.getSystemResource),在Java9之前会拿到 jar:file:<path-to-jar>!<path-to-file-in-jar>这类格式的URL Schema,而Java9之后则变成了 jrt:/<module-name>/<path-to-file-in-module> 其他一些问题[6] 对于新的项目,使用模块构建似乎是值得的,但现状...
