In this example, we will write a Java code to iterate over an ArrayList using the Iterator interface.

List (ArrayList) Iterator Example

Here is the example to iterate over an ArrayList using Iterator interface:

package com.java.tutorials.collections;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class IteratorExample {
    public static void main(String[] args) {
  
        List<String> fruits = new ArrayList<String>();
        fruits.add("Banana");
        fruits.add("Apple");
        fruits.add("Mango");
        fruits.add("Orange");
  
        Iterator<String> iterator = fruits.iterator();
           while (iterator.hasNext()) {
           String fruit = (String) iterator.next();
           System.out.println(fruit);
   
          if("Banana".equals(fruit)) {
              iterator.remove();
          }
       }
       System.out.println(fruits);
    }
}

Output:

Banana
Apple
Mango
Orange
[Apple, Mango, Orange]
