Comment on Anon tries programming in Java

Honestly, I prefer C to Java, it’s incredibly simple without all the BS that Java throws at you:

interfaces - compiler will fail if you provide the wrong types; w/ Java, figuring out what types to pass is an effort unto itself
functions - everything needs to be in a class; even callback functions are wrapped in a class (behind the scenes if you use modern Java); in C, you just pass a function
performance - Java uses a stop the world GC, which can cause issues if you have enough data churn; in C, you decide when/if you want to allocate or free memory, no surprises

There are certainly some bad parts, but all in all, when I run into an issue in C, I know it’s my fault, whereas in Java, there are a million reasons why my assumptions could be considered valid, and I have to dig around the docs to find that one sentence that tells me where I went wrong w/ the stuff I chose.

That said, I prefer Rust to both because:

get fancy stack traces like I do in Java (I really miss stack traces in C)
compiler catches most of my stupid mistakes, Java will just throw exceptions
still no stupid interface hell, I just satisfy a specific trait and we’re good
generally pretty concise for what it is; I can rarely point to a piece of syntax and say it’s unnecessary

I use:

Python - scripting and small projects
Rust - serious projects or things that need to be fast
Go - relatively simple IO-heavy projects that need to be pretty fast

Java has been absent from my toolbox for well over a decade, and I actively avoid it to this day because it causes me to break out in hives.

For over a decade?

In the last decade java finally is starting to catch up! The latest java releases have finally given us the ability to pass through a function, and work more functional.

And you can choose any GC you want, even less “stop the world” ones, but who got the time to figure out which GC they actually want… The memory allocation from C is what haunts my dreams more than the GC from java.

Still, I really want to give Rust a look, if only I gave myself enough time.

  Which AFAIK is still a class under the hood. That doesn’t particularly matter for developers, but it’s still odd.
  
  But honestly, if I’m going to use anything on the JVM, I’ll just use Kotlin. Java is kind of catching up, but Kotlin is just so much cleaner IMO. But if I’m not stuck w/ the JVM, I’ll use one of the others I mentioned.
  
  The memory allocation from C
  
  Eh, it’s honestly not so bad, provided you’re using it for the type of work where C is suited. For most embedded work, I just pass on the stack, so no need to malloc() or free() most of the time. If I’m building a larger program, I’ll probably not use C, because it just doesn’t have the features I want for larger-scale development work, and I definitely won’t use C++ because that’s a nightmare of conflicting legacy features.
  
  Rust is my go-to if I know it’ll be large-ish and I don’t have any particular restraints on where it’s going to run (i.e. not on a microcontroller or something). The compiler catches a lot of my bugs, the result is fast, and now that I’m comfortable with it, I’m pretty productive with it. It does have a bit of a learning curve, but it’s way better than when I started with it (around the 1.0 launch).
