In this section of tutorial we will learn how to reset the ArrayList contents.We will create an example to display the contents of the ArrayList after resetting it.- 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
import java.util.ArrayList;
import java.util.Iterator;
import java.util.ListIterator;
public class reset {
public static void main(String[] args) {
char alphabet = 'a';
ArrayList list = new ArrayList();
while (alphabet != 'z') {
list.add(alphabet++);
}
ListIterator it = list.listIterator();
while (it.hasNext()) {
System.out.print(it.next() + " ");
}
System.out.println();
while (it.hasNext()) {
System.out.print("* " + it.next() + " ");// it doesnot work
}
while (it.hasPrevious()) {
it.previous();
}
while (it.hasNext()) {
System.out.print("." + it.next() + " ");// it works
}
}
}
