Accurate even with poorly formatted Java code
Q: Are the original Java files altered in any way?
Your existing code is left completely intact. The new
VB.NET 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
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, 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 are the most common adjustments necessary after conversion?
Most Java platform or library function calls are not converted. However,
we do convert a subset of the Java string, keyboard I/O, math,
and utility function calls. Also, many Java container
classes are converted to .NET container classes.
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 "ToDo" comment. You must manually
Some reference type comparisons are
converted, but you will need to manually change some equality
symbols to "Is". The VB compiler makes these adjustment
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.
