Java Interview Prep:How to safely remove elements from a List 📝#shorts #dsa #java #shortvideo #short

Are you making this common Java mistake? 😱 Trying to remove an element from a List while iterating through it with a for-each loop will crash your program!

In this short, we cover why this happens and how to safely use Iterator and iterator.remove() to avoid the dreaded ConcurrentModificationException. This is a classic concept tested in software engineering interviews!

💻 Code Snippet:

Iterator String itr = list.iterator();
while (itr.hasNext()) {
if (itr.next().equals("target")) {
itr.remove();
}
}
