Java interview warm-up: What happens when you remove an item inside this enhanced for-loop?

Preparing for a Java switch started feeling like a second full-time job.

Core Java, collections, concurrency, streams, JVM, Spring, DSA, system design… I would study one topic for a few days, get busy with work, and lose momentum again.

The problem wasn’t finding more material. It was revising consistently.
