The primary emphasis is on core Java concepts that can be directly and immediately applied to automate testing processes.

Please note that this course does not provide an in-depth exploration of test automation frameworks such as Selenium. It also avoids the traditional "Hello World" introductory method, as it is not focused on general application development. Instead, the goal is to enable participants to start performing test automation as quickly as possible. If you already possess Java proficiency and wish to proceed directly to testing with Selenium, we recommend our: Introduction to Selenium (https://www.nobleprog.com/introduction-selenium-training) course.

Note that this training does not cover user interface (UI) topics.

Even seasoned Java developers often lack a comprehensive grasp of the security services provided by Java and the various vulnerabilities that affect web applications built with it.

This course not only introduces the security components of the Standard Java Edition but also addresses security concerns within Java Enterprise Edition (JEE) and web services. The discussion begins with the fundamentals of cryptography and secure communication before diving into specific services. Various exercises cover both declarative and programmatic security techniques in JEE, as well as transport-layer and end-to-end security for web services. Participants engage in practical exercises to explore and apply the discussed APIs and tools firsthand.

The course also examines and explains the most common and severe programming flaws in the Java language and platform, along with web-related vulnerabilities. Beyond typical bugs made by Java programmers, the security vulnerabilities covered include language-specific issues and problems arising from the runtime environment. All vulnerabilities and associated attacks are demonstrated through accessible exercises, followed by recommended coding guidelines and mitigation techniques.
