Core Java in Telugu | Java Programming - P80 - Java Stream Operations – 1 | filter, map, sorted, peek, count, forEach

In this video, we take a deep dive into the most commonly used Stream operations in Java. This is Part 1 of the Java Stream Operations series where we break down both intermediate and terminal operations with real code examples and explanations. ✨ What You'll Learn: 👉 What are Streams in Java? 👉 ✅ Stream sources: Creating streams from Collections & Arrays 👉 ✅ Intermediate operations: • filter() – filter elements based on condition • map() – transform elements • sorted() – sort the stream • peek() – debug or inspect values during pipeline 👉 ✅ Terminal operations: • count() – count elements • forEach() – process each element ⭐⭐ List of Interview Questions on Stream Operations in Java – Part 1 ⭐⭐ ❓ What are the common ways to create a Stream in Java? ❓ How can you create a Stream from a Collection? ❓ How can you create a Stream from an Array? ❓ What is the purpose of the filter() operation in a stream? ❓ How does map() transform data in a stream pipeline? ❓ What is the difference between map() and filter() in streams? ❓ What kind of function does map() take as an argument? ❓ What does the peek() operation do in a stream? ❓ When should you use peek() in a stream pipeline? ❓ Is peek() a terminal or intermediate operation? ❓ What does the sorted() operation do in a stream? ❓ How can you sort stream elements in descending order? ❓ What happens if you use sorted() on objects without implementing Comparable? ❓ How does count() work as a terminal operation? ❓ How does forEach() differ from traditional for-loops? ❓ What is the return type of forEach()? ❓ Can forEach() modify the original collection? ❓ What is the difference between forEach() and peek()? ❓ How does the order of stream operations affect performance? ❓ Can we use filter() and map() together in the same pipeline? ❓ Are stream pipelines evaluated lazily? ❓ Can you chain multiple intermediate operations together? ❓ What is short-circuiting in the context of stream operations? ❓ What happens if you forget to add a terminal operation to a stream? ❓ Can we debug a stream pipeline? How does peek() help in debugging? By the end of this video, you’ll understand how these operations work and how to combine them effectively in a stream pipeline. 👉 This is part of a series. Stay tuned for upcoming videos on advanced stream operations like collect, reduce, flatMap, anyMatch, and more! 💬 Questions to Think About: ❓What’s the difference between map() and filter()? ❓When should you use peek() in a real-world scenario? ❓How does the order of stream operations affect the result? 🔔 Subscribe and turn on notifications so you don’t miss Part 2! 👍 Like if this helped 📤 Share with your fellow Java learners 💬 Got questions or need clarification?
