The android.util.SparseArray class in Java is a data structure optimized for memory usage. It is used to store key-value pairs, similar to a regular array or map, but it is specifically designed to handle situations where the keys are integers.
SparseArray is more memory-efficient than using a HashMap or List because it avoids auto-boxing of keys and values. It silently handles the expansion and contraction of underlying arrays as needed, resulting in fewer wasted memory spaces.
This class is commonly used in Android development when dealing with large collections of data where the keys are integers, such as when storing and managing resource IDs or managing data for adapters in RecyclerView or ListView.
