macOS Cocoa (Obj-C) with Java or Python

[laptin]

Hi,

I was wondering how can you call java APIs or python APIs (either one) in Objective-C?

I know you could do this in cocoa:

id MyJavaClass = NSClassFromString(@"java.util.Vector");
id vector = [[MyJavaClass alloc] init];
[vector add"one item!"];
NSLog(@"item 1=%@", [vector get:0]);
[vector release];

this prints "item 1=one item!" in console, but that's it.
Does anyone has other examples? Like how to pass in arguments to a java constructor, like so:

id MyStringClass = NSClassFromString(@"java.lang.String");
id mystr = [[MyStringClass alloc] init"Hello World"];

But this does not work, i do not know why.

Any help is appreciated.

For Python, you could check out the PyObjC project. For calling Java from Cocoa, check out this page.

You can also call Python or Java from a Cocoa application using NSTask. Use NSFileHandle and NSPipe if you need to communicate with that process as it runs. AppleScript is also an option but probably not what you want here.
