ArrayList: A resizable array implementation in Java Collections. Allows dynamic size changes.
Example:

import java.util.ArrayList;
ArrayList list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Cherry");
System.out.println(list);
list.remove(1);
System.out.println(list);
for (String fruit : list) {
 System.out.println(fruit);
}
