Learn Java language grammar + basic programming skills + data structures at the same time.

This course is for those preparing for the CosPro Level 1 exam, covering the COS Pro Level 1 sample problems released by the exam organizer, YBM Net Co., Ltd.

Learn Java programming language by solving 100 problems. The entire course consists of 5 parts. In this course, Part 3, you will solve problems on the topic of functions and OOP.

Scala allows you to write much more concise and robust code quickly, while still leveraging the experience you have gained as a Java developer. This course is designed for Java developers to quickly understand the overall look of Scala based on their existing Java knowledge. If you are an existing Java developer, you can learn Scala very easily.

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.

It explains the basic concepts step by step and helps you gain practical knowledge by practicing creating various applications that actually run in a web environment. If you complete this course, you will be ready to work as a programmer.

Knowing design patterns will make it easier to learn not only Spring but also many other technologies and programming languages. It will also help you develop more flexible and reusable object-oriented software.

Through this course, you can learn how to run Java applications more efficiently and effectively solve performance issues that may arise.

Explanations that mix multiple concepts can cause confusion. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So in this course, only one new concept appears at each stage, and I meticulously designed a sequential structure between concepts so that no other unfamiliar concepts appear. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. For 3 hours, you'll learn 180 core concepts in the designed order.
