How do I convert a Ruby (.rb) file to Java?

Paste your Ruby source code into the converter on this page, select your preferred Java version (e.g., Java 8 or 11), and click 'Convert'. The tool translates Ruby syntax such as modules, blocks, and method definitions into Java equivalents. You can then download the resulting .java file and integrate it into your project.

Why should I convert Ruby code to Java?

Converting Ruby to Java lets you run your code on the Java Virtual Machine (JVM), giving you access to the vast Java ecosystem, including Spring, Android, and enterprise libraries. Java's static typing and mature tooling improve performance, maintainability, and scalability for large applications, while preserving your original business logic.

How does the RB to JAVA converter handle Ruby-specific features like blocks and dynamic typing?

The converter maps Ruby's dynamic dispatch to Java using interfaces, enums, or reflection, and translates blocks to anonymous classes or lambda expressions. Symbols become String constants or enums, and duck typing is converted to interface-based code. Note that metaprogramming and monkey patching may require manual refinement, as these concepts have no direct Java counterpart.
