Is Kotlin for Java Developers Still Relevant?

The last update landed June 10, 2026 — and for a Programming Languages course, freshness is the first thing to verify. An updated date means the instructor still maintains the material; a stale one means you learn last year's version of the tools.

The 4.5 rating from 35,023 learners suggests the content holds up in practice — ratings at that level rarely survive contact with outdated material. The entry bar looks low, which makes this a reasonable first course in the topic rather than a capstone.

What the Course Actually Delivers in 16h 30m

Total runtime is 16h 30m of video, which you work through self-paced with lifetime access. The published syllabus lists 3 outcomes — headlined by create Kotlin programs; understand the differences between Java and Kotlin; understand how Java and Kotlin programs interoperate. With 35,023 learners enrolled, the pacing and explanations have been stress-tested at scale.

Is the Price Fair After the Coupon Discount?

The real comparison is not list versus coupon, but coupon versus the next-best course at the same sale price — and on ratings-per-dollar, this one compares well. $159.99 is the list price, but Udemy courses at this level almost never sell at list. This coupon brings it to $9.99 — a 94% cut worth $150.00. Spread over the runtime, that is about $0.61 per hour of instruction — cheaper than a coffee per study session.
