u have to forget j++. try eclipse or jdeveloper. j++ has nothing more to serve u
different
than jdeveloper or a powerfull eclipse instalation with some useable pluggins.
and also
thay are free and platform independent, can run every platform with a singe jre
installation. j++ has been depricated and ms will not give any support on this
product.
and also u have to know that j++ is not java, it was a primitive c#, nothing
more,
has its own jvm build by ms and has no more support for next generation java
libraries.
util, swing ...
