An AI system that grades and reviews your code in 5 seconds - imagination becomes reality. This course is an all-in-one project that builds a **'GitHub PR Automatic Analysis and Grading Bot'** using Spring AI. When a student submits an assignment (Pull Request), the server detects it and AI analyzes the code changes (Diff). The grading results are then stored in the database, feedback is automatically posted as GitHub comments, and students can check their results on a dedicated dashboard. From backend to AI integration and frontend (Vaadin) - all with Java! This is the ultimate introductory guide for all developers who want to complete their own AI service from A to Z.

This book provides an in-depth study of various intermediate-level Java features necessary for practical work, using example code.

This course is a learning process that involves studying the fundamental theories of data structures by directly implementing them through JAVA programming. Rather than simply learning theory, it is structured to enable a deeper understanding of data structure principles by implementing them with actual code. Learners will theoretically learn core data structure concepts such as arrays, stacks, queues, lists, trees, and graphs, while simultaneously implementing them in JAVA code to experience their actual operation processes. Through this approach, rather than rote memorization, learners can develop logical thinking skills and problem-solving abilities, enjoying the synergistic effect of learning programming and data structures together. 👉 Upon completing this course, learners will master the basic concepts and structural characteristics of data structures, as well as the ability to implement and apply them in actual development environments, establishing a foundation for designing more efficient and robust programs.

This course is a process of learning about container virtualization technology, one of the four components that make up Cloud Native Architecture. It is a learning process that understands the basic concepts of container virtualization, which is the best way to deploy and operate Microservice applications, and covers Docker technology, which is the most widely known container virtualization technology. In addition to theoretical learning about the essential content required to deploy and operate applications developed in MSA form, you can understand how actual Docker containers work through related practical examples. In this course, you can also learn about various elements such as Docker Security and Logging that have not been covered in other existing lectures, and in the final practical project, you can build services (Harbor + Argocd) that can be linked to Docker technology and deploy applications to practice the core operating environment required for DevOps.

This is an Oracle course, one of the top 3 databases. Even if you are learning databases for the first time, you can easily learn.

From Docker, Kubernetes to microservices, CI/CD, and service mesh, you can easily learn not only the basic theory but also the actual application implementation through examples. By organizing only the core contents necessary for actual use, it provides a starting point for learning about the element technologies covered in the lecture.
