How to Remove an Element from Java ArrayList

In this example, we will use ListIterator to remove an element while traversing through elements of ArrayList in Java.

Source Code

package com.beginner.examples;

import java.util.ArrayList;
import java.util.ListIterator;

public class RemoveAnElementUsingListIterator {

	public static void main(String[] args) {
		
		//create ArrayList.
		ArrayList arrayList = new ArrayList();
		
		arrayList.add("A");
		arrayList.add("B");
		arrayList.add("C");
		arrayList.add("D");
		
		System.out.println("Before removing B, ArrayList contains");
		for(int intIndex = 0; intIndex < arrayList.size(); intIndex++) {
			System.out.println(arrayList.get(intIndex));
		}
		
		//Get an object of ListIterator using listIterator() method.
		ListIterator listIterator = arrayList.listIterator();
		
		//remove the element of "B".
		listIterator.next();
		listIterator.next();
		listIterator.remove();
		
		System.out.println("After removing B, ArrayList contains");
		for(int intIndex = 0; intIndex < arrayList.size(); intIndex++) {
			System.out.println(arrayList.get(intIndex));
		}
		      
	}

}

Output:

Before removing B, ArrayList contains
A
B
C
D
After removing B, ArrayList contains
A
C
D
