Java Basics - User Id Cookie and Database | Java Spring Tutorial смотреть онлайн

Continuing the discussion of databases we create a User Id Cookie by generating a Universal Unique Identifier (UUID) both in Java and JavaScript. We learn about cookies and how to set them in both tiers. We then tie everything together by saving the information to the database and writing a test case.

All you need to know to learn Java with this course is basic grade school algebra and the ability to install software. We start from the very basic concepts of programming to build simple Java applications. Once completed we will connect this course to the "Modern Java Course" and "Debugging at Scale in Production" course.

This course updates weekly, please use the comments section below to ask questions and make requests. We'll try to help.
