A 2D list can be iterated in one of the two methods that follow Using Loops Using iteratorMethod 1: Employing LoopsThere are two ways for you to traverse over a 2D list (a list of lists).The first is the usage of a nested for-each loop. For this, we must first retrieve the 2D ...
// ListIterator - traverse a list of elements in either forward or backward order // An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, // and obtain the iterator's current position in the list. System.out.println("...
Print List in Java Using the Enhanced for Loop One of the simplest and most readable methods to iterate through list elements is using the enhanced for loop. The enhanced for loop, also known as the for-each loop, simplifies the process of iterating through collections, including lists. Its...
