FAQ

Q: Are the original VB.NET files altered in any way?

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

Q: What is the conversion accuracy?

Our accuracy is very high, but there will be significant adjustments required for all but the simplest conversions. There are no direct equivalents for some aspects of VB.NET. 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 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 way to convert VB6 to Java is to first upgrade to VB.NET, 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 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 about .NET UI code?

The converter does not convert .NET UI types due to the lack of similarity between these types and Java UI types.

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

  • VB to Java Converter converts only some .NET types to Java equivalents. The converter offers options to use your own custom replacements.
  • There are no simple equivalents to VB events in Java, so these must be refactored.
  • Since Java lacks a preprocessor, all code dependent on conditional compilation needs to be refactored so that the functionality can be achieved in other ways.
  • VB LINQ query syntax is not converted since this feature is not available in Java (but LINQ method syntax is partially converted).
  • VB 'Structure' is converted to Java 'class', since Java does not include value types. We add a 'clone' method to the Java class to try to reproduce the same behavior as .NET value types, but adjustments may still be required.
  • If the VB project did not have 'Option Strict On' set, then you'll likely have a number of cases where different types are compared with each other - the converter will sort out most cases, but some may need adjustment.
  • Although some On Error GoTo statements are converted, some elements of classic VB unstructured error handling (On Error Resume Next, On Error GoTo -1, etc.) are not converted. These statements are marked as a 'ToDo' task.
  • 'When' statements in 'Catch' blocks (which have no equivalent in Java) must be manually adjusted. These are commented out and combined with a warning comment.
  • VB nullable logic cannot be converted since the necessary null-value logic must be applied to every aspect of expressions containing the nullable variable or method call. The only aspect of nullable instances that is converted is the declared type - the corresponding Java wrapper type is used for nullable primitives (e.g., the Java wrapper type 'Integer' is used for VB Integer? or Nullable(Of Integer)).
