Скачать или смотреть How to use averagingInt, summingInt and summarizingInt methods of Collectors? | Java 8 streams

Welcome to our channel! In this tutorial, we’ll explore powerful aggregation techniques using the `averagingInt`, `summingInt`, and `summarizingInt` methods of `Collectors` in Java 8 streams. These methods provide convenient ways to calculate average, sum, and obtain statistical summaries of numeric data in streams efficiently.

What You Will Learn:
*Introduction to Java 8 Streams:* Understand the foundational concepts of the Stream API and its benefits for data processing in Java.
*Using `averagingInt` Method:* Learn how to compute the average of integer values in a stream using the `averagingInt` collector.
*Exploring `summingInt` Method:* Explore how to calculate the sum of integer values in a stream using the `summingInt` collector.
*Understanding `summarizingInt` Method:* Discover how to obtain statistical summaries (count, sum, min, max, average) of integer values in a stream using the `summarizingInt` collector.
*Practical Examples:* Follow along with practical examples that demonstrate the application of `averagingInt`, `summingInt`, and `summarizingInt` methods in real-world scenarios.
*Combining Methods:* Learn how to combine these collectors with other stream operations like filtering and mapping to perform complex data analysis tasks.
*Performance Considerations:* Understand the performance implications of using `averagingInt`, `summingInt`, and `summarizingInt` efficiently in your Java applications.
*Functional Programming Principles:* Gain insights into functional programming concepts such as immutability and lambda expressions, which are fundamental to working effectively with Java 8 streams.

Why Learn `averagingInt`, `summingInt`, and `summarizingInt` Methods of Collectors?
Mastering these methods allows you to write concise and efficient code for numeric data aggregation tasks. Whether you're calculating average ratings, total sales, or statistical insights from datasets, these collectors streamline your Java programming tasks.

Example Scenario:
Imagine you have a stream of sales data where each element represents the sales amount. Using `summingInt`, you can quickly compute the total sales, while `averagingInt` provides the average sales amount. Meanwhile, `summarizingInt` gives you a comprehensive statistical summary of the sales data.
