java2python

Simple but effective tool to translate Java source code into Python and Rusthon.

The java2python package can translate any syntactically valid Java source code file. The generated Python code is not guaranteed to run, nor is guaranteed to be syntactically valid Python. However, java2python works well many cases, and in some of those, it creates perfectly usable and workable Python code.

For more information, read the introduction. To install, refer to the installation page.

There are lots of docs, plenty of tests, and many options for controlling code generation.

If you're looking for old releases, check the downloads link above.

Here's a very simple example:

$ cat HelloWorld.java

// This is the HelloWorld class with a single method.
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, world.");
    }
}

Convert Java Program To Python

$ j2py HelloWorld.java

Python Output

#!/usr/bin/env python
""" generated source for module HelloWorld """

#  This is the HelloWorld class with a single method.
class HelloWorld(object):
    """ generated source for class HelloWorld """

    @classmethod
    def main(cls, args):
        """ generated source for method main """
        print "Hello, world."

if __name__ == '__main__':
    import sys
    HelloWorld.main(sys.argv)

Convert to Rusthon

$ j2py --rusthon HelloWorld.java
