Android: what is the difference between Bundle Vs java.util collections like HashMap

Question

What is the difference between Bundle Vs java.util collections like HashMap?

Answer 1

A Bundle in Android is a tool the apps use to handle resources. It has built in structure that lets the OS search bundles hierarchically to find a specific resource.

Yes, it is essentially a hash map, but it designed to be a specialized Android component, and not a general purpose data structure.
