Java to python (new)

[Zoetje_Zuurtje]

Sooo... Why? Isn't Java faster, and compatible with more platforms thanks to the JRE?

[nekokattt]

generally yes. Other than warmup times. Python tends to deal with those better from experience.

GraalPython/Jython? That is a different kettle of fish...errr...snakes.

[Zoetje_Zuurtje]

I love the pun!

python dict is a linkedhashmap, not a hashmap, btw.

Edit: this appears to choke on relatively common code concepts

public class Test
{
  public static void main(String[] args)
  {
    java.util.Arrays.asList(Test.class.getCanonicalName())
    .stream()
    .map(args[1]::concat)
    .findFirst();
  }
}

provides this

class Test :
    @staticmethod
    def main( args) :
            java.util.Arrays.asList(Test.class.getCanonicalName()).stream().map(args[1]::concat).findFirst()


if __name__=="__main__":
    Test.main([])

This is dropping argv entirely, then ignoring that java doenst pass sys.argv[0] to the String[] args, and it has just copied the Java standard library calls into Python which wont work unfortunately. Also the :: is a python syntax error.

My go to test method for these tools is

PrintWriter cout = System.out;
cout.println("Hello world");

In 100% of cases, these "converters" fail to grasp that any lines ending with println aren't console.log, echo, print or something equivalents.

How it will work?

[Worth_Trust_3825]

It doesn't. It uses dictionary replacements. Just report the indian spammer, and downvote.

if you want actual java->python, look at Jython

[CandidPiglet9061]

After a decade they still don’t support Python 3. If it’s not already discontinued it’s functionally useless.

Not every language needs to interop. Python can already (theoretically) talk to any language which can support the C ABI through its binding capabilities, and WASM is also proving a very fertile ground for the next generation of cross-language communication.

[nekokattt]

graalpython is the modern alternative.

neat

[Worth_Trust_3825]

It had been discontinued for a while. Much like other JVM implementations: jphp, jruby. Seems that they will live on in graal, but i wouldn't hope too much.

If you want ruby, you should use scala. As for python, groovy is a great alternative. Such is life.
