Perform basic data analysis tasks using Java streams

In this 1-hour long project-based course, you will learn how to create a Java Stream object based on an array of data, and understand the distinction between terminal and intermediate stream operations. You will iterate through the data stream using the forEach method, and use a range of Stream methods to perform logical operations on the data stream. You will perform basic statistical calculations on a stream of numeric data, and string operations on a stream of string data. You will learn how to use the map, filter, and reduce Stream methods. Finally, you will learn how to load a CSV file, the COVID vaccination dataset, and turn it into a data stream, and perform basic exploratory analysis of the data.

Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Reviews summary

Basic java streams for data analysis

According to students, this 1-hour project-based course provides a largely positive introduction to performing basic data analysis tasks using Java streams. Learners particularly praise the clear explanations of core concepts like map, filter, and reduce, and the effective distinction between terminal and intermediate stream operations. The hands-on approach, utilizing a real-world dataset, is a key strength for many. However, a significant number of students encountered technical friction with environment setup, which sometimes detracted from the overall learning experience, especially for those outside the North America region or with less technical comfort. Despite this, the course is seen as concise and practical for a quick grasp or refresh of Java streams.

Provides a quick and effective overview in a short time.

"Excellent short course! It delivered exactly what it promised."

"The course is concise and gets straight to the point."

"Perfect for a quick refresh on Java streams or an introduction."

"The pace was just right for a short course."

Hands-on project with real-world data enhances learning.

"I appreciated the hands-on approach and using a real-world dataset like the COVID vaccination data..."

"The course is concise and gets straight to the point. It covers the basics well and the COVID dataset example was a nice touch..."

"I liked how it tied into a practical data analysis scenario. The hands-on coding was engaging."

"This course is concise, practical, and the real-world data example was a great way to show applicability."

Excellent explanations of core Java stream operations.

"The instructor explains `map`, `filter`, and `reduce` very well."

"I found the explanations of terminal vs. intermediate operations particularly helpful."

"The course made it clear. The project structure was effective, and the concepts themselves were explained adequately."

"The explanations were clear, and I truly understood the difference between intermediate and terminal operations by the end."

Technical difficulties with course environment setup common.

"My only minor gripe was the setup of the environment, but once past that, it was smooth."

"I encountered significant issues with the provided IDE setup. It felt clunky and took a good portion of the hour just to get things running..."

"I found the setup very confusing. I'm not in North America and had problems with the environment, which made following along difficult."

"The technical setup instructions were not clear enough for a beginner. Spent too much time troubleshooting environment issues..."
