A cross-platform language is developing computer software, which is developed to . work across multiple computing platforms .

Windows. Note: As of April 8, 2014 Microsoft stopped supporting Windows XP and therefore it is no longer an officially supported platform. Users may still continue to use Java 7 updates on Windows XP at their own risk, but support will only be provided against Microsoft Windows releases Windows Vista or later.

Java works across multiple platforms by utilizing something known as the Java Runtime Environment (JRE) and a JVM or Java Virtual Machine . A Java Virtual Machine is an application or software device that is used to execute Java code or “applets” as provided, in this case, by websites.

Both Java and Python compile to bytecode and run in virtual machines. This isolates code from differences between operating systems, making the languages cross-platform.
