Java - iterate through Arraylist using iterator
0 points
In this article, we would like to show you how to iterate through ArrayList using iterator in Java.
Quick solution:
xxxxxxxxxx1
Iterator<String> myIterator = myArrayList.iterator();2
3
while (myIterator.hasNext()) {4
System.out.print(myIterator.next() + " ");5
}
In this example, we create an iterator for letters ArrayList to display all the elements in the proper order.
xxxxxxxxxx1
import java.util.*;2
3
public class Example {4
5
public static void main(String[] args) {6
List<String> letters = new ArrayList<>();7
8
letters.add("A");9
letters.add("B");10
letters.add("C");11
12
// create an iterator13
Iterator<String> myIterator = letters.iterator();14
15
// display values after iterating through the ArrayList16
System.out.println("The iterator values of the list are: ");17
while (myIterator.hasNext()) {18
System.out.print(myIterator.next() + " ");19
}20
}21
}Output:
xxxxxxxxxx1
The iterator values of the list are: 2
A B C
