How does dropWhile() work? - Cracking the Java Coding Interview #javalanguage #javacoding #javatips

Explains how the `dropWhile()` method works in Java's Stream API. It acts as a gate that stays closed while a predicate evaluates to false, then opens permanently once the predicate returns true, passing all remaining elements downstream. Key caveats: behavior is undefined for unordered streams (any subset may be dropped), and using it on ordered parallel streams is a stateful operation that can significantly degrade performance.
