Construct a Linked List
containing name: CPP, Java, Python and PHP. Then extend your java program to do
the following:
Display the contents of the
List using an Iterator
Display the contents of the
List in reverse order using a ListIterator.
import java.util.LinkedList;
import java.util.List;
import java.util.ListIterator;
import java.util.Iterator;
public class LinkedListDemo {
public
static void main(String[] args) {
//
Create a linked list of names
List<String> names = new LinkedList<>();
names.add("CPP");
names.add("Java");
names.add("Python");
names.add("PHP");
//
Display the contents of the list using an Iterator
System.out.println("Contents of the List using an Iterator:");
Iterator<String> iterator = names.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}
//
Display the contents of the list in reverse order using a ListIterator
System.out.println("\nContents of the List in Reverse Order using a
ListIterator:");
ListIterator<String> listIterator =
names.listIterator(names.size());
while (listIterator.hasPrevious()) {
System.out.println(listIterator.previous());
}
}
}
