Top 50+ Java Streams Coding Questions - Count the occurrence of each word in given sentence #java8

📝 Count the Occurrence of Each Word in a Sentence Using Java Streams | Java 8 Stream API Tutorial 📝

In this video, you'll learn how to count the number of occurrences of each word in a sentence using Java Streams. This is a classic and widely-used example of applying functional programming concepts to real-world text processing problems.

We’ll demonstrate how to split a sentence into words and use Collectors.groupingBy() with Collectors.counting() to generate a word-frequency map — all using concise and expressive Java 8+ stream operations.

🧠 What You’ll Learn:
✅ How to split a sentence into words using split("\\s+")
✅ How to stream and normalize words for accurate counting
✅ Using Collectors.groupingBy() to group identical words
✅ Counting the frequency of each word using Collectors.counting()
✅ How to handle punctuation, case sensitivity, and empty strings

💡 Why This Is Important for Java Developers:
🔹 Word counting is a common task in text analysis, log processing, NLP, and search indexing
🔹 Demonstrates how to process textual data using Java Streams
🔹 Helps you master grouping and aggregation patterns in functional Java
🔹 A frequently asked problem in Java interviews and real-world data projects

👨‍💻 Who Should Watch This Video:
✔️ Java developers working with text or log data
✔️ Students preparing for Java coding interviews
✔️ Developers transitioning to functional programming with Java 8+
✔️ Anyone looking to write cleaner and more efficient Java code

📺 Watch This If You Want To:
🔹 Learn how to count word frequency from any given sentence
🔹 Avoid nested loops with modern stream-based solutions
🔹 Practice grouping and mapping in Java 8+
🔹 Understand how to handle real-world input and edge cases
