Hi, I have recently been programming using the Sun java sdk but for a
project at college, I have to use Visual J#.net. What are the main
differences between the two? Which one is harder? Is there any difference
between the two API's?

Thanks

In brief:-

1. Microsoft do not (yet) have any version of Java. Following the
agreement between Gates and Bill McNealy, that may change in future.

2. Visual J# is not even a close attempt at Java - it is a totally
different language designed (as is C#) to produce the .NET intermediate
code (rather than the Java intermediate code).

3. The .NET intermediate code does not run on a Java Virtual Machine (it
uses a .NET virtual machine). This virtual machine is NOT operating
system independent (as the JVM is).

4. Java does not use an API. J# does (it uses the .NET API set).

5. Both are workable - but only Java will produce system-independent
code and applications. Neither is particularly "hard".

As a matter of interest, the better comparison is between J# and J2EE
(with or without Tomcat etc.).
