问题:

is there a tool which can convert actionscript3 source code to java source?

回答1:

I ran into this page awhile ago because I needed an actionscript to java converter too. I wrote one myself. It's very simple and requires manual adaptation after conversion (as most such converters do), but it does a good job of automating the boring stuff. You can find it on my blog.

回答2:

I believe Haxe (which has similar syntax to AS3, also based on the ECMA Specification) is able to compile to Java (as well as a slew of other languages and bytecodes). It requires learning a new language, but it may be worth it.

回答3:

You should explain why you want to convert from AS3 to Java. I think, the typically way is to convert from Java to AS3, e.g. with Gas3.

回答4:

You will be able to do this via Haxe in near future. First use as3hx to convert AS3 to Haxe, and then you can convert Haxe to Java via Haxe compiler. Haxe/Java was promised to be relased in this year.
