What technologies are used in teams? Is Kotlin included?

Teams working with Java often use the following technologies:

• Java SE and Java EE (Jakarta EE) for server-side application development.
• Spring Framework (Spring Boot, Spring MVC, Spring Data) — to simplify development and microservices deployment.
• Hibernate or JPA — for database interactions.
• Maven or Gradle — for build and dependency management.
• Docker and Kubernetes — for containerization and orchestration.
• CI/CD tools (Jenkins, GitLab CI).

Regarding Kotlin — yes, Kotlin is increasingly used in Java teams, especially for server applications and microservices, due to its conciseness and JVM compatibility. Many teams are gradually adopting Kotlin, especially if the project requires increased productivity and modern syntax.

Example of a simple Kotlin service with Spring Boot:

@RestController
class HelloController {
    @GetMapping("/hello")
    fun hello() = "Hello, Kotlin!"
}

Thus, Kotlin often complements or gradually replaces Java in modern teams.
