J2ObjC is described as 'Open-source command-line tool from Google that translates Java code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java code to be part of an iOS application's build, as no editing of the generated files is necessary' and is an app in the development category. There are 1 alternatives to J2ObjC for Mac, Windows and Linux. The best J2ObjC alternative is XMLVM, which is both free and Open Source.
The goal of XMLVM is to offer a flexible and extensible cross-compiler toolchain. Instead of cross-compiling on a source code level, XMLVM cross-compiles byte code instructions from Sun Microsystem's virtual machine and Microsoft's Common Language Runtime.
