"Kotlin: Seamless Java Interop, Less Verbose, and Intuitive to Learn"

4.5/5

What do you like best about Kotlin?

It's interpolable with Java which makes it very easy to adopt with existing Java codebases and packages and integrations.

It is very less verbose than Java but at the same time strictly types and addresses most of the major issues with Java, it's basically Java on steroids.

Given now AI agents and LLMs write a lot of code, it is easy for LLMs to understand the code as well.

In terms of learning curve as well, I feel it is very natural and intuitive

I feel using Kotlin actually gave a good ROI given especially in our org we have kotlin on both Android as well as Backend with Spring boot. Review collected by and hosted on G2.com.

What do you dislike about Kotlin?

Nothing major, I just hope people adopt Kotlin more and more given it's way more better than Java, so having a larger community would be better.

Also I think it's Interop with Java is excellent, but not always perfect Review collected by and hosted on G2.com.

What problems is Kotlin solving and how is that benefiting you?

I’m part of the Backend team, and we use it with Spring Boot, so I’m sharing a backend engineer’s perspective. It addresses several pain points we commonly run into with Java development, including excessive boilerplate, null-safety concerns, and overall verbosity. Its seamless interoperability with Java also makes it easy for us to adopt without disrupting our existing ecosystem.

From my perspective, this results in code that’s more concise, readable, and maintainable, along with faster development and fewer runtime issues related to null handling. Review collected by and hosted on G2.com.
