ArrayList Iterator Example
import java.util.ArrayList;
import java.util.Iterator;
public class IteratorExample {
public static void main(String[] args) {
ArrayList<String> arr= new ArrayList<String>();
arr.add("Shivam");
arr.add("Raju");
arr.add("Mukesh");
arr.add("Bela");
Iterator<String> itr=arr.iterator();
// hasNext()
//Returns true if there are more elements. Otherwise, returns false.
while (itr.hasNext()) {
/*
* Returns the next element.
* Throws NoSuchElementException if there is not a next element
* To avoid this exception call hasNext() before next()
*/
System.out.println("Element Is:"+itr.next());
}
}
}
Output:
Element Is:Shivam
Element Is:Raju
Element Is:Mukesh
Element Is:Bela
