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

➕ Find the Sum of Unique Numbers in a List Using Java Streams | Java 8 Stream API Tutorial ➕ In this video, you’ll learn how to find the sum of all unique numbers in a list using the Java 8 Stream API. This task is especially useful when working with datasets where duplicates can skew results, and it’s a common real-world and interview scenario that tests your understanding of stream filtering and collection. We’ll walk through how to use Collectors.toSet() to eliminate duplicates, and then apply stream operations to sum up the distinct values cleanly and efficiently. 🧠 What You’ll Learn: ✅ How to remove duplicates from a list using streams ✅ How to convert a collection into a Set to ensure uniqueness ✅ How to stream over unique values and calculate the sum ✅ The difference between distinct() and Collectors.toSet() ✅ Clean and idiomatic Java code for summing unique integers 💡 Why This Is Important for Java Developers: 🔹 Ensures accurate calculations in applications like reporting, analytics, and financial logic 🔹 Demonstrates mastery of stream pipelines and intermediate operations 🔹 Helps write more concise, readable, and modern Java code 🔹 A common scenario in Java coding interviews and technical assessments 👨‍💻 Who Should Watch This Video: ✔️ Java developers working with collections and data transformation ✔️ Students preparing for Java interviews or coding challenges ✔️ Professionals learning to write clean functional code ✔️ Anyone working with numeric lists where data accuracy is key 📺 Watch This If You Want To: 🔹 Learn how to efficiently sum only the unique elements in a list 🔹 Avoid manual iteration and eliminate duplicates using modern Java 🔹 Master Java 8 features like Collectors.toSet(), mapToInt(), and sum() 🔹 Practice a real-world use case in stream-based data processing 📌 Subscribe to the channel for more Java stream challenges, functional programming techniques, and interview prep content. 💬 Have a twist in mind — like finding the sum of numbers that appear exactly once?
