Hello, I got an assignment to benchmark Java vs Kotlin. I was thinking I could benchmark Collections insert and remove speed such as ArrayList.add. Is it a good idea or does Kotlin just use internally Java colletions? If so, what else could I benchmark to show difference between Java and Kotlin?

does Kotlin just use internally Java colletions

That's pretty much it

Hmm, what could I benchmark then? Streams vs Sequences?

Kotlin and Java performance will be pretty much the same when executing on the JVM. What you should "benchmark" is lines of code per feature and amount of bugs per line of code

Ah, okay. Might be a bad topic for my assignment then 😕

Why do you need to check for performance?

It’s my school assignment. I got “Benchmarking” and I chose Java vs Kotlin, thought it could show some interesting stuff but I guess I should have done more research

Is that benchmark specific to performance?

No, I don’t think so, we are learning about Benchmarking in general

You c ould benchmark Kotlin vs Kotlin itself

I think that is a good idea. Do you have some more examples? Maybe mutable and immutable?

Maybe

List

operations vs

Sequence

operations (filter + map + fold ... in a row)

Just learned about inline stuff, that could be great to benchmark, could show some solid stuff.

Try to find out why X performs better than Y, and not only that it does. You'll study the language more if you do that

Yeah, my teacher told me to look at the bytecode generated so I guess I’ll try to look into that

They teach kotlin in University?

It's probably not specific to Kotlin

Yeah possible

Yeah, it’s a course “performance and reliability” 🙂

Awesome :) futuristic curriculum lol, my college still teaches C as a modern language xD

as modern? 😄 sounds odd. I mean C is awesome but not as modern language 😄

Yeah lol that is the sad situation of cs education in India

I see C as a modern language tho

Hmm it's cool as it gives good foundation

Leonardo, so I talked to my tutor, and he told me I can do the suggested Kotlin vs Kotlin. He recommended I try sequences vs list. And then try something like different order of operations such as map and then filter vs filter and then map, if the order is optimized

@Hoanghun5 Nice! Do you know the differences between List and Sequence?

I know that sequence should do the operations lazily and list doesnt

I think that's pretty much it

Is there a difference if I use Sequence on ArrayList or LinkedList? That was another idea my tutor had

There might be a difference depending on the operations you're executing

awesome, so another thing I could do .. I am supposed to show 15 scenarios.

Another idea is to benchmark Kotlin vs Java compilation time and memory usage. And how incremental builds improve compilation.
