Automated Python to Java translation

Question

Is there a tool out there that can automatically convert Python to Java   Can Jython do this

User · Answer

Yes Jython does this  but it may or may not be what you want

User · Answer

It may not be an easy problem  Determining how to map classes defined in Python into types in Java will be a big challange because of differences in each of type binding time    duck typing vs  compile time binding

User · Answer

to clarify your question   From Python Source code to Java source code    I don t think so      or from Python source code to Java Bytecode   Jython does this under the hood

User · Answer

Actually  this may or may not be much help but you could write a script which created a Java class for each Python class  including method stubs  placing the Python implementation of the method inside the Javadoc  In fact  this is probably pretty easy to knock up in Python   I worked for a company which undertook a port to Java of a huge Smalltalk  similar-ish to Python  system and this is exactly what they did  Filling in the methods was manual but invaluable  because it got you to really think about what was going on  I doubt that a brute-force method would result in nice code   Here s another possibility  can you convert your Python to Jython more easily  Jython is just Python for the JVM  It may be possible to use a Java decompiler  e g  JAD  to then convert the bytecode back into Java code  or you may just wish to run on a JVM   I m not sure about this however  perhaps someone else would have a better idea
