Top 50+ Java Streams Coding Questions - Find the sum of the first two numbers in given list

➕ Find the Sum of the First Two Numbers in a List Using Java Streams | Java 8 Stream API Tutorial ➕ In this video, you'll learn how to calculate the sum of the first two elements in a list of integers using the Java 8 Stream API. This is a simple but effective use case to demonstrate how stream operations like limit(), mapToInt(), and sum() work together to perform fast and readable numeric computations. Whether you're preparing for interviews or optimizing small tasks in your applications, this example will show you how to write clean, concise, and functional Java code. 🧠 What You’ll Learn: ✅ How to limit a stream to the first N elements using limit() ✅ How to convert a stream of integers to an IntStream using mapToInt() ✅ How to use the sum() terminal operation to get total ✅ Edge case handling when the list contains fewer than two elements ✅ How to write efficient one-liners with Java Streams 💡 Why This Is Important for Java Developers: 🔹 Summing specific elements is a common operation in data filtering, financial apps, and input validation 🔹 Demonstrates efficient use of numeric stream operations 🔹 Helps solidify your understanding of stream slicing and aggregation 🔹 Frequently seen in Java coding interviews and practice challenges 👨‍💻 Who Should Watch This Video: ✔️ Java beginners looking to get hands-on with Stream API ✔️ Developers working on data processing or aggregation tasks ✔️ Students preparing for Java coding interviews ✔️ Anyone transitioning to a more functional and expressive style of Java 📺 Watch This If You Want To: 🔹 Learn how to sum a subset of elements from a list using streams 🔹 Replace verbose loops with clean stream pipelines 🔹 Understand key stream operations: limit(), mapToInt(), and sum() 🔹 Practice one of the most common micro-tasks in Java development 📌 Subscribe to the channel for more Java stream coding problems, interview prep, and real-world Java tutorials. 💬 Got a variation in mind, like summing the top N largest numbers or using parallel streams?
