Improve Variable Naming and Method Description in Box.java

[jturfanbasis]

File: src/main/java/com/webforj/samples/components/Box.java

Description: The Box.java file contains non-descriptive variable names and method naming inconsistencies that reduce code readability and maintainability. Additionally, the boxDestroy() method name does not adhere to standard Java naming conventions.

Issues:

Variable Naming:

1. int num: Lacks clarity on its purpose. The suggested name is boxNumber.
2. boolean vis: Should be renamed to isVisible or similar for better readability and alignment with Java boolean naming conventions. However, it seems to be unused in the current implementation. If it is not intended to be integrated into the logic, it should be removed to avoid confusion and improve code clarity.

Method Naming:

1. Method boxDestroy(): Does not follow standard Java naming conventions. Suggested name is destroyBox()

Expected Behavior:
Variable names should be descriptive and self-explanatory.
Method names should adhere to Java naming conventions.

Proposed Solution:
Rename num to boxNumber and vis to isVisible or similar.
Rename boxDestroy() to destroyBox().
