Develop and deploy servers using Java, Spring Boot, JPA, MySQL, and AWS. While developing web applications, you will learn all the background knowledge, theories, and various technologies required for server development, as well as the meaning of various options, the history of Spring Boot, and the changes in the latest version.

Through this lecture, you can learn about the characteristics and background of the Kotlin language, grammar and operation principles, usage examples, and things to be careful of when using Java and Kotlin together.

We will refactor a web application built with Java + Spring Boot to Kotlin + Spring Boot and implement additional requirements. In the process, we will use Junit5, SQL, JPA, and Querydsl, and cover the pros and cons of various methods from the design and implementation perspectives.

It covers major updates from Java 9 to Java 21 in detail. It will be continuously updated as newer versions are released up to Java 31.

You will be able to understand all the language features of Kotlin. After taking the course, you will be able to freely program using advanced Kotlin technologies such as generics, delegation and deferral, DSL, and reflection.

Through this lecture, I hope to understand the core of the Kotlin language and avoid the mistake of being blocked by the language when developing Android apps.

Develop a scalable order processing system with real-time event streaming capabilities using Spring Boot 3.x + Kotlin to build a Kafka cluster, leveraging PostgreSQL CDC, Debezium Connect, and Apache Avro schema.

In this course, you will learn Kotlin syntax, how to safely convert Java projects to Kotlin, and how to code in a Kotlin-like manner. Learn Kotlin based on practical code and use it yourself to enjoy its advantages.

This is a course on the Kotlin programming language. Recently, Google officially added Kotlin as an Android development language. However, there is still a lack of Kotlin translations or materials for learning Kotlin in Korea. However, if you go to kotlinlang.org, the content on Kotlin is well organized, although it is in English. So, I studied kotlinlang.org myself and organized the content into a video. I think it will be helpful to other people studying Kotlin, so I organized the material.

You will be able to learn about popular programming techniques and features, not just Kotlin grammar. It is also good to learn the concept of Android TDD through MVP.

This course will give you a quick overview of the combination of Kotlin and Spring by implementing simple functions.

Kotlin mastery via virtual payment server course.

Currently, Android can be developed using the Java and Kotlin languages. The same Android application can be developed using either language. This course covers most of the content from basic to advanced Android application development, and all code is written using the Kotlin language starting from the basic content. We also use Material 3, Google's latest UI library. This course mainly covers menus, Android application components, threads, and Fragments among the entire Android curriculum, and future courses are planned to cover more in-depth topics. Soft Campus will always strive to provide the latest lectures. Thank you.
