How to Get an Iterator For ArrayList in Java

Here we will use Iterator to iterate through the elements of ArrayList object in Java.

Source Code

package com.beginner.examples;

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

public class GetIteratorExample {

	
	public static void main(String[] args) {
	
		ArrayList al = new ArrayList();
		
		al.add(1);
		al.add(2);
		al.add(3);
		al.add(4);
		al.add(5);
		
		Iterator iterator = al.iterator();
		
		//This iterator can only remove elements
		while(iterator.hasNext())
		{
			Integer element = iterator.next();
			
			iterator.remove();
			System.out.println(element);
		}
		
		System.out.println("Remove all:----->"+al);
	}

}

Output:

1
2
3
4
5
Remove all:----->[]
