Inserting an element in an ArrayList refers to adding a new element at a specific position within the ArrayList. This operation shifts existing elements to accommodate the new element and maintains the order of the remaining elements.
Imagine you have a row of chairs in a classroom, each occupied by a student. If you want to add another student between two existing students, you would need to shift all the students after that position to make room for the new student while keeping everyone in their original order.
ArrayList: A dynamic array-like data structure that can grow or shrink dynamically as elements are added or removed.
Index: A numerical value representing the position of an element within an ordered list or array.
Resize: The process of changing the size (capacity) of a data structure, such as an array or ArrayList, to accommodate more or fewer elements.
