ListIterator - Java Beginners
ListIterator Hi,
What is the use of ListIterator in Java? Provide me example code of ListIterator.
Thanks
Hi Friend,
It reads the object of the list in both the directions i.e forward and backward
Java ArrayList listIterator listIterator() method is used to return a ListIterator reference
of the given list.
Using this reference all elements of the list can be
iterated...]);
list.add(ar[3]);
ListIterator i=list.listIterator();
while(i.hasNext
Java Previous Iterator
Java previous Iterator function is present in the listIterator Interface.
ListIterator is special iterator for the list.
previuos method allows to get the one before element of the list.
listIterator allows traversing in the both
Java listItrator
Java listItrator What is the significance of ListIterator? Iterator : Enables you to cycle through a collection in the forward direction only, for obtaining or removing elements.
ListIterator : It extends Iterator
Iterator Java Reset
iterator interface doesn't have any reset method.
In the listIterator the previous method can be used to rsest the
list.
Example of Java Reset Iterator... != 'z') {
list.add(alphabet++);
}
ListIterator it = list.listIterator
Avl tre problem code - Java Beginners
() {
// override to go 75% faster
return listIterator(0);
}
/**
* Gets a ListIterator over the list.
*
* @return the new iterator
*/
public ListIteratorlistIterator() {
// override
Iterator Java Remove
remove()method removes the last element of the list.
This method is used with both Iterator and listIterator.
It is used with next() or previous() method.
Example Java Remove Iterator
import java.util.ArrayList;
