I have some years of experience with C++ and now need to learn java. I
appreciate if you could advise me on how to get started. In the past,
I used to work with Visual C++ 5.0 and 6.0 and have recently switched

Is it the right place to start?

Many thanks for any comments.

J# is not Java,

True.

That depends on the definition of Java.

It is a pretty good implementation of the Java 1.1
language.

The runtime environment is not Java as it runs with .NET and not
with a JVM.

and not well supported by Microsoft - it is only there
as a migration from Microsoft's J++ (now withdrawn) to C#.

False. J# is a language in its own right (neither Java now C#, though its
syntax is Java-like). Nowadays, the .NET framework comes with J# support
(it used to be an add-on) and the .NET online documentation includes J#
examples; that is, J# support is improving as time goes on.

It is not quite obvious to me that "it is only there as a migration"
and "a language in its own right" exclude each other.

J# is a separate package in both .NET 1.1 and 2.0, 3.0 is not a full
..NET at all and 3.5 is still in beta.
