Key Benefits

The Most Comprehensive VB.NET to Java Converter


Q:   Is the original VB.NET project altered in any way?

Your existing code is left completely intact.  The new Java files are written to the new location that you specify.

Q:   What is the conversion accuracy?

Our accuracy is the highest in the industry, but there will be significant adjustments required for all but the most trivial conversions.  There are no direct equivalents for some aspects of VB.  Read the rest of the FAQ to get an idea of a few things that are not converted.  VB to Java Converter is intended to reduce the amount of work you'll have to do to convert VB code to Java, but it is just the first step.

Q:   Does VB to Java Converter convert VB6 projects to Java?

No.  The most effective and safest way to get from VB6 to Java is to use an upgrade tool (3rd party or the VS 2008 Upgrade Wizard) on your VB6 code, and then use VB to Java Converter on the resulting VB code.

Q:   How are VB.NET methods with optional parameters converted?

Overloaded methods are created and the 'Optional' keywords are removed.  Missing arguments are replaced by the defaults specified by the original VB parameter list.

Q:   Are VB.NET delegates converted?

Yes - try out our Free Edition to see the conversion details.  We convert delegate declarations to interface declarations and references to delegate instances to lambdas.

Q:   Are VB.NET case statements with range expressions handled?

Yes, VB 'Select Case' blocks containing non-ordinal or range expressions are converted to Java 'if-else' blocks.  Other 'Select Case' blocks are either converted to Java 'switch' statements if the expressions are constant (a requirement in Java) or to Java if-else blocks otherwise.

Q:   Are VB.NET ByRef parameters converted?

Yes - try out our Free Edition to see the conversion details.  We substitute a wrapper type (using Java generics) for the parameter type and adjust all references to the parameter in the defining method and all calls to the method.

Q:   What are the most common adjustments necessary after conversion?
