Program Overview: What is Kotlin for Java Developers?
Kotlin rewards Java developers who learn its idioms. This program teaches the language properly: null safety, expressive syntax, coroutines for concurrency, and smooth Java interop.
Led by Kotlin engineers, the program moves from syntax to null safety, collections, and coroutines. Guided labs run in every module on realistic service code.
The program closes with a capstone full build: a Kotlin service module with null-safe code, coroutines, and tests, reviewed by the instructor.
Teams leave writing Kotlin, not Java-in-Kotlin: safe, expressive, and concurrent where it counts.

Kotlin for Java Developers Course Topics and Program Outline
6 modules, 20 instructor-led hours, and 3 guided labs that move Kotlin for Java Developers from theory to dependable team practice.
Built by Edstellar with engineers who build production systems in Kotlin
Built by engineers who build production systems in Kotlin, shaped around your stack and use cases.
We check where your team stands on Kotlin today, so the program targets real gaps instead of repeating what they know.
Instructor-led sessions teach software development concepts in order, with demos and Q&A in every module.
guided labs give your team coached repetition on realistic software development scenarios with instructor review.
The capstone full build proves the learning: a Kotlin service module, built, reviewed, and ready to take back to work.
From baseline to job-ready in 20 hours.

Training Delivery Modes: Virtual, Onsite and Hybrid
Instructor-led delivery in hybrid, onsite, or live virtual formats, with hands-on labs in every session.
Hybrid Training
Split your cohort between the training room and a live virtual feed. Every session is instructor-led, with hands-on labs in each module and the same curriculum for both groups.
- Live instruction in every session
- Onsite workshops for guided labs
- Virtual sessions for distributed teams
- One cohort or split batches
Onsite Training
Your trainer comes to your premises. Sessions stay practical: hands-on labs run in the room with the instructor beside each team.
- Trainer at your premises
- Guided guided labs with the instructor beside each team
- Team collaboration in one room
- Agenda tuned on the spot
Live Virtual Training
Join from anywhere in live instructor-led sessions. Labs run in shared environments so the trainer can see every screen and coach in real time.
- Join from anywhere, live
- Shared lab environments with trainer coaching
- Sessions recorded for review
- Same curriculum, same hours
Need a training format that works for your team?
Full days, half days across weeks, or split by module. Tell us the delivery window and we schedule the cohort around it.
Learn from industry experts.
Every session is led by a practitioner who has run monitoring for models in production, not a generalist working from slides.
