Java Lecture 42: Parallel Streams & Primitive Optional | Fork/Join, Spliterator & Performance ☕💻🚀

☕ Master Parallel Streams & Primitive Optionals in Java!

In Lecture 42, you'll learn:

✅ Sequential vs Parallel Streams
✅ "parallelStream()" & Parallel Processing
✅ Fork/Join Architecture & Work-Stealing
✅ "Spliterator" Interface
✅ "trySplit()" & "tryAdvance()"
✅ Stateless vs Stateful Operations
✅ Primitive Optionals: "OptionalInt", "OptionalLong", "OptionalDouble"
✅ Boxing vs Unboxing Overhead
✅ When to Use Parallel Streams
✅ Race Condition Prevention
✅ CPU Utilization & Performance Optimization
✅ Java Interview Questions

This lecture focuses on high-performance Java processing, explaining how parallel streams divide work, how the ForkJoinPool supports work-stealing, how "Spliterator" partitions data, and why primitive Optional types can avoid boxing overhead. The notes also emphasize using parallelism mainly for large, CPU-intensive, independent workloads and benchmarking before parallelizing.

✅ Optional Chaining for Clean Null-Safe Code
✅ Parallel Streams Introduction
✅ Sequential vs Parallel Ex*****on
✅ ForkJoinPool Architecture
✅ CPU Utilization & Performance
✅ Thread Safety in Parallel Streams
✅ When to Use Parallel vs Sequential Streams
✅ Optional & Parallel Streams Interview Questions

Learn how Optional helps write clean, crash-free code by safely handling potentially absent values, while Parallel Streams enable concurrent processing across multiple CPU cores. Master these Java 8+ concepts for modern Java development, backend programming, performance optimization, and coding interviews.
