The Microsoft Java Language Conversion Assistant (JLCA) is a tool that automatically converts existing Java-language source code to C# for developers who want to move their existing applications to the Microsoft. NET Framework Original KB number: 819018 Summary As its name suggests, XMLVM converts the original bytecode into XML which is later transformed into bytecode for a different VM or into source code for web or iOS applications.This article describes that the Java Language Conversion Assistant (JLCA) is available for download.

NET or Java bytecode, or into JavaScript, Python or Objective-C/C++ source code. J2ObjC is an alpha project but it is already used by several unspecified projects inside Google.Īnother similar tool is XMLVM, a cross-compiler converting Java. J2ObjC can manage unused objects in several ways but it uses reference counting with auto-release pools by default. One of the main problems converting Java code to Objective-C is garbage collection.

Destructor Generator: adds dealloc or finalize methods, depending on GC option selected.

Inner Class Converter: pulls inner classes out to be top-level classes in the same compilation unit.

Anonymous Class Converter: modifies anonymous classes to be inner classes, which includes fields for the final variables referenced by that class.

Initialization Normalizer: moves initializer statements into constructors and class initialization methods.

IOS Method Converter: maps method declarations and invocations to equivalent Foundation class methods.

IOS Type Converter: converts types that are directly mapped from Java to Foundation classes.

Autoboxer: adds code to box numeric primitive values, and unbox numeric wrapper classes.

Rewriter: rewrites Java code that doesn't have an Objective-C equivalent, such as static variables.

Dead Code Elimination: eliminates unused code from the JAR file.

J2ObjC makes a number of steps in generating Objective-C code:

Generated code can be profiled, tested and analyzed with Xcode Instruments, like any other iOS app. The generated code uses the iOS Foundation Framework and can be integrated with Xcode either via an external build project with a separate makefile, or by adding a build rule to an existing project. While server code could theoretically be translated, J2ObjC currently supports only client-side development. The tool does not generate iOS UI code because its authors believe that “the only way to get a world-class, fast iOS UI is to write it in Objective-C using Apple's iOS SDK frameworks,” and due to intricacies dealing with such code. J2ObjC solves part of the problem being able to convert business logic Java code into its corresponding Object-C/C++ source code that does not require editing in order to be used.

While web client apps based on GWT can share non-UI code with Android apps, the same apps had to be rewritten for iOS from scratch. Google has open sourced J2ObjC, a transpiler converting Java source code to Objective-C/C++ source code for the iOS platform.Īccording to the J2ObjC’s wiki, the project was started out of frustration dealing with different code bases for web, Android and iOS applications.
