Iterators & Enhanced for
Traverse collections with Iterator and enhanced for. Learn safe removal during iteration and common pitfalls.
Overview
Iterator gives step-by-step control to walk through a collection. Enhanced for (for-each) is shorter and clean for reading elements. Use Iterator when you need to remove safely during traversal.
Iterator vs for-each
- Iterator: use when you may remove items or need fine control.
- Enhanced for: best for read-only loops.
- Never structurally modify the collection inside enhanced for.
