What are the main classes used for handling data collections in array structures?

In Android, the following main classes are often used for working with data collections:

• ArrayList — a dynamic array that allows adding and removing elements.
• LinkedList — a linked list, convenient for frequent insertions and deletions.
• HashMap — a collection of key-value pairs with quick access by key.
• HashSet — a set of unique elements.
• SparseArray — an optimized version of HashMap for int type keys, often used to save memory.

Example of using ArrayList:

ArrayList<String> list = new ArrayList<>();
list.add("Android");
list.add("Kotlin");
for (String item : list) {
    System.out.println(item);
}
