ArrayList Iterator Example



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
