Deleting an element refers to removing it from a data structure like an array or list. In relation to traversing and deleting from an ArrayList, deleting an element at index i involves eliminating it from the collection while maintaining order for subsequent iterations.
An index refers to the position at which an element is stored within a data structure like an array or list. It starts from 0 for the first element and increments by 1 for each subsequent element.
An ArrayList is a resizable array that stores elements of a specific type. It allows dynamic adding and removing of elements, making it useful when the size of the collection may change.
Traversal refers to the process of accessing each element in a data structure, usually in a sequential manner. In relation to an ArrayList, it involves iterating through all the elements stored within it.
