hi Palmyra,
Welcome Aboard
I want suggest something:
1) Download Eclipse:
although you have something other to learn,
for a beginner, it is very useful have "someone" that:
suggests how to complete a statement,
which class members you can refere in that point for the current object,
have directely the signaling about syntax/compile error.
(Eclipse is what I use, there are also other development tools)
2) have a goal:
Java (just core) is incredibly wide, respect other languages I knew. I read in your profile that you "surf" in DB area:
start here using JDBC to access to DB that you know.
3) begin with no graphic output:
Write the output of your DB queries on stdout.
Later choose one of the graph environment: AWT or SWT or SWING
4) continue to study about inheritance and polymorphism:
but ignore it, now, writing programs.
When Java will be for you more friendly,
you could appreciate their powerful.
5) remain now inside Eclipse:
later you can export the same program, with external library
if used, to pack it in a JAR, and launch it from win/linux command line.
.....
however we are here !
ciao
