Top 50+ Java Streaming Coding Interview Questions - How to debug streams using peek()? #coding

🔍 How to Debug Streams Using peek() in Java | Java 8 Stream API Explained 🔍

In this video, you’ll learn how to use the peek() method in Java Streams to debug and trace the execution of intermediate operations like map(), filter(), and sorted().

The peek() method is often misunderstood or underused — but it can be a powerful tool for visualizing the internal flow of stream pipelines, making it easier to identify logic issues and data transformation errors during development or testing.

🧠 What You’ll Learn:
✅ What peek() does and when to use it
✅ Difference between peek() and forEach()
✅ How to trace intermediate stream operations step-by-step
✅ Debugging stream chains involving map(), filter(), sorted(), etc.
✅ Best practices and gotchas of using peek() safely

💡 Why This Is Important for Java Developers:
🔹 peek() is essential for understanding lazy evaluation in streams
🔹 Helps debug complex stream logic without breaking the pipeline
🔹 Encourages a clean, side-effect-aware approach to troubleshooting
🔹 Commonly discussed in Java interviews to assess debugging mindset

👨‍💻 Who Should Watch This Video:
✔️ Java developers new to the Stream API
✔️ Engineers struggling with unexpected behavior in stream pipelines
✔️ Interview candidates who want to understand stream internals
✔️ Developers building complex data processing logic using Java 8+

📺 Watch This If You Want To:
🔹 Master the correct and safe use of peek() in Java Streams
🔹 Visually debug chained stream operations
🔹 Learn how data flows through each stage of a stream pipeline
