Is javax compatible with Java 17

I'm happy to respond in English for once!

To answer your question: yes, the javax package is compatible with Java 17. In fact, the javax package has been maintained and updated throughout Java versions, including Java 17.

The javax package was introduced in Java 1.1 (around 1997) as a way to group related packages together under a single namespace. Over time, various javax packages have been added or removed as part of the Java Standard Library (JLS).

In Java 17, you can still use the same javax packages that were available in previous versions, such as:

javax.swing: for creating GUI applications

javax.servlet: for building web applications using servlets and JSPs javax.persistence: for working with databases using Java Persistence API (JPA) javax.xml: for working with XML documents

These packages, among others, continue to work as expected in Java 17, allowing you to develop applications that leverage their functionality.

That being said, it's worth noting that some older javax packages might not be fully compatible with Java 17 or might require additional configuration to work correctly. For example:

The javax.microedition package was deprecated in Java 11 and removed from the JLS in Java 14. You won't find this package in Java 17. Some older javax packages, such as javax.xml.registry, were part of the Java EE (Enterprise Edition) platform, which is no longer included with the JLS. These packages are not compatible with Java 17.

In summary, most javax packages available prior to Java 17 continue to work in Java 17. However, it's essential to verify compatibility and any potential changes or limitations when using these packages in your Java 17 applications.

I'd be happy to help!

Java allows you to manage dependencies and modules using the Java Platform Module System (JPMS). This system is based on the concept of modules, which are self-contained units that encapsulate libraries and applications.

In order to add multiple modules in your Java project, you can follow these steps:

Create a module declaration file: First, create a module-info.java file for each module you want to include. In this file, specify the dependencies of the module using the requires keyword. Add the modules to the module-path: Next, add the paths of these module declarations files to your Java application's module-path. You can do this by setting the -p or --module-path option when compiling or running your Java program.

For example, let's say you have two modules named "math" and "graphics". Your module declaration files for each module might look like this:

// math/module-info.java

requires java.base;


requires java.xml;


export com.example.math;


// graphics/module-info.java


requires java.base;


requires javafx.graphics;


export com.example.graphics;

In the above example, the math module depends on the java.base and java.xml modules, while the graphics module depends on the java.base and javafx.graphics modules.

Add the modules to your Java application: Once you have declared each module and added them to your project's module-path, you can use these modules in your Java application. For example: 
// Main.java (part of a larger application)

import com.example.math.MathUtil;


import com.example.graphics.GraphicRenderer;


public class Main {


public static void main(String[] args) {


MathUtil math = new MathUtil();


GraphicRenderer renderer = new GraphicRenderer();


// Use the modules as needed


math.calculateSomething();


renderer.renderSomething();


}


}

In this example, you can use the MathUtil class from the "math" module and the GraphicRenderer class from the "graphics" module in your Java application.

Note that JPMS is a relatively new technology, and there may be some limitations or quirks to consider when using modules in your Java project. For more information on how to manage dependencies with Java modules, I recommend checking out the official Oracle documentation:

I hope this helps! Let me know if you have any further questions.
