Following up from a previous post, I just started using Sams Teach
Yourself Java 6 in 21 days. So far it seems very nice, very similar to
my old VB book of the same series.
However, the text editor it comes with is buggy (for example, doesn't

I am reading a book about Java . It says that :
An interface may not define any instance fields. Fields are an
implementation detail, and an interface is a pure specification
without any implementation .

Hi Guys,  Good news is that as many as 12 courses from top

I am currently developing a java application that has a combo box and
a list box. I have a menu options which is called Locate Data File.
When I click on this menu item it is supposed to clear the data from
the list box and from the combo box and then load a dialogue box.

I have a java program which expects a different class (BeanHome.class)
file from a jar. I have added this jar into my classpath. But still I

I'm just looking for confirmation that the following is horrible
application design.
We have an application (web-based) that contains a JSP which contains
an applet which calls some VBScript which activates an ActiveX control

Following recent discussions here about benchmarking and when Java's
performance is worst, I proposed the idea of symbolic computation because
this entails very high allocation rates for short-lived objects when
written in an idiomatic functional style and Java should be uniquely ...

I am considering using static imports in my Java code and was
wondering whether there was a performance cost or resource issues
associated with doing so.  Can anyone tell me about how Java
implements the "import static" syntax that was introduced in Java

I was given a bunch of XML files with the task of converting them to
spreadsheet (helped by OpenOffice, of course). The one part that I am
missing is a Class that loads the *.xml file and provides me with the
ability to make queries and retrieve the data using different methods.

I'm working on a program that will scan the names of old time radio shows at
Archive.org and give me a listing of the shows and later, a listing of the
episodes available.  It's the Java version of a quick version I wrote in
Perl.
