FAQ
Q: Are the original Java files altered in any way?
Your existing code is left completely intact. The new VB.NET files are output to the new location that you specify.
Q: What version of Java is converted?
We attempt to convert as much as possible and are continually updating the converter to handle newer Java features. However, many new Java features have no VB equivalent so the output will require adjustments.
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 Java. Read the rest of the FAQ to get an idea of a few things that are not converted. Java to VB Converter is intended to reduce the amount of work you'll have to do to convert code to VB.NET, but it is just the first step.
Q: Can the converter produce VB6 code?
No - only VB.NET code is produced.
Q: How are anonymous inner classes handled?
Anonymous inner classes are converted to VB nested private classes, but if the interface is a functional interface, then the interface is converted to a delegate and the anonymous inner class is converted to a lambda.
Q: Are Java functional interfaces converted?
Yes - try out our Free Edition to see the conversion details. We optionally convert Java functional interfaces to VB delegates.
Q: What about Java UI code?
The converter does not convert Java UI types due to the lack of similarity between these types and .NET UI types.
Q: What are the most common adjustments necessary after conversion?
- Java to VB Converter converts only some Java library types to .NET equivalents. The converter offers options to use your own custom replacements.
- VB does not allow assignments within expressions, but Java does (e.g., while ((x = y()) > 0) assigns a value to x as part of an expression). The converter will convert some cases, but will mark other more complex cases with a 'task' comment. You must manually adjust these.
- Some reference type comparisons are converted, but you will need to manually change some equality symbols to "Is". The VB compiler makes these adjustment requirements obvious.
- Java's event handling model has no direct equivalent in VB.
- Java wildcard generics have no equivalent in VB, unless used in a method declaration parameter list.
- Java local classes cannot be declared within methods in VB. These are marked with a comment.
