Why is it sometimes necessary to edit XML configuration without changing the original Java code?

Editing XML configuration without changing the original Java code is often required for flexibility and ease of application maintenance. This allows:

• Modifying settings (such as connection parameters, paths, security settings) without recompiling and redeploying the code.
• Quickly adapting the application's behavior to different environments (development, testing, production).
• Separating logic and configuration, which improves readability and maintainability.

For example, in the Spring Framework, XML is often used to define beans and dependencies. By changing the XML, you can connect different implementations of interfaces or change parameters without editing the Java code.
