The Java Streams forEach() & forEachOrdered() Terminal Operations

This video discusses two Java terminal operations: forEach() and forEachOrdered(). Both are run-to-completion methods that produce side effects and return no value. While forEach() may not maintain the original order of elements, especially in parallel streams, forEachOrdered() guarantees this "encounter order", even in parallel streams. Despite their utility, these methods have limitations, such as causing null pointer exceptions if the collection to store results is not initialized, and introducing race conditions when applied on parallel streams. I therefore recommend using collection-based terminal operations like collect() as a safer, more efficient alternative to handle concurrency and ensure thread-safety.
