Question

Accepted Answer

Android activity life cycle is the sequence of states an activity goes through.

The life cycle includes states like onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy().
Each state has a specific purpose and can be used to manage the activity's behavior.
Collections in Java are data structures that store and manipulate groups of objects.
Examples of collections include ArrayList, LinkedList, HashSet, and HashMap.
Collections provide methods for adding, removing, and accessing elements in the group.
They can also be used to sort, search, and filter the elements.
