Loop incrementation refers to the step in a loop where the counter variable is updated to move on to the next iteration. It ensures that each iteration processes different data or performs different actions until a certain condition is met.
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.
