What is `ClassLoader` delegation model and what is the parent-first loading order?

Accepted Answer

The `ClassLoader` delegation model follows the order of Bootstrap → Extension/Platform → Application, where each loader delegates to its parent first before loading itself. This ensures that classes are loaded in a hierarchical manner, allowing for dependencies to be resolved efficiently.
