[Bug]: Project build / compilation fail when we try to run any class.

[am-opensource-learner-void]

Hi,
Whenever we try to run any class locally the IDE gives compilation error for many classes due to not properly following coding standard.

I will take ownership and try to fix all issues, so next time whenever a new / existing contributor try to run any file then there wont be any compilation issue.

Regards,

Main Problem: Public class names and filenames do not match

Java requires that a public class must be in a file with the same name as the class.

Class AreaRect is public, should be declared in a file named AreaRect.java

You do have areaRect.java, but the file name starts with a lowercase 'a'.
Java is case-sensitive, so areaRect.java is not same as AreaRect.java.

To fix:
Rename all your files so the filename matches the public class name exactly (case-sensitive).
Remove the public modifier if you want to keep multiple classes in one file (not common for large programs).

Also fix this issue shown in the log:
Your file is not inside a directory named area, but your class declares package area
You either need to remove or fix the package declaration, or put the file inside a folder called area/ inside your Programs folder.

If you're not using packages explicitly, just remove the package declarations at the top of each file.
