Master Terminal Operations in Java Stream API | forEach, Collect, Reduce & More | Java 8 Streams

Welcome to Dev Portal!

In this tutorial, we dive deep into Terminal Operations in the Java Stream API - the final step in stream pipelines that process data and produce results. Whether you're a beginner or an experienced developer, this video will enhance your understanding of how to use terminal operations effectively to write cleaner and more efficient Java code.

What You'll Learn in This Video:
1️⃣ What are Terminal Operations?
2️⃣ The difference between intermediate and terminal operations.
3️⃣ Key terminal operations explained with examples:
* forEach: Apply actions to each element.
* collect: Gather stream elements into collections.
* reduce: Aggregate elements into a single result.
* count: Count the total elements in a stream.
* toArray: Convert streams into arrays.
* min & max: Retrieve minimum and maximum values.
* anyMatch, allMatch, noneMatch: Check conditions on stream elements.
* findFirst & findAny: Retrieve specific elements.
4️⃣ Advanced grouping and summarizing using Collectors.

Example Highlights:
✅ Filter unique names and collect them into a list.
✅ Calculate the sum of numbers using reduce.
✅ Group students by grades using Collectors.groupingBy.
