Lists are an ordered collection of elements in Java. Conceptually those are similar to Linked list in C with methods to add, delete elements. In this post, we are only going to look at how to iterate the through Lists in Java.
Method 1: Lets create and iterate simple ArrayList using for loop
List<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("How");
myList.add("are")
myList.add("you?")
for (String listElement : myList) {
System.out.println(listElement);
}Method 2 : Using Iterator / ListIterator
The List interface provides a special iterator, called a ListIterator, that allows element insertion and replacement, and bidirectional access in addition to the normal operations that the Iterator interface provides. A method is provided to obtain a list iterator that starts at a specified position in the list.
List<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("How");
myList.add("are")
myList.add("you?")
ListIterator<String> mIterator = myList.listIterator();
while(mIterator.hasNext()) {
System.out.println(mIterator.Next());
