Arraylist Hacks: removing element from arraylist | Quick ArrayList Modification | ArrayList Tutorial

In this tutorial, we are going to learn how to safely remove elements from an ArrayList in Java while using a for loop. Each time I tried to remove the element Java would throw a concurrent modification exception and my program would fail. There is actually a really good reason this happens. If you understand what is happening underneath the hood when we use a for loop it all makes sense. We are using an iterator to loop over the collection while using the collection to remove the element and this never updates the iterator to say "I removed an element". In this tutorial, we will look at one way to solve it and then an even easier way to fix this problem. In Java 8 a new method was added to the collections interface called removeIf. This method takes a predicate and makes it super easy for us to remove items from a collection if they meet some criteria. 👋🏻Connect with me: Github: https://github.com/JavaaTechSolutions LinkedIn: https://www.linkedin.com/in/javatech-solutions-b44b352b7 🎟 Join this channel to get access to perks: https://www.youtube.com/channel/UCm82_YpE8-MPvB-uLkoWZxA/join 🎉 Don't forget to like, subscribe, and hit the notification bell to stay updated with our programming tutorials.
