List in Java provides the facility to maintain the ordered collection. Source code to sum the elements of a List. The array is a basic structure in Java whereas an ArrayList is a part of the Collection Framework in Java. There are two ways to access ArrayList in java, we can access the elements randomly and sequentially. This method returns the next element in the list and advances the cursor position. We can access the element of an array using the index number. The get() method of List interface in Java is used to get the element present in this list at a given specific index. Inside the loop we print the elements of ArrayList using the get method.. This method returns the previous element in the list and moves the cursor position backward. extends E> c).
