I suspect most of your questions would be better answered on the Java
Newbies forum, on Stack Overflow, or on your class/course's message boards.

OK, so the program you're trying to run is an example program from a
textbook.

That's a ridiculously tiny screenshot, and you haven't explained
when/how you got that error. Was it when you ran the example program
according to the instructions given in its JavaDoc, using

java -classpath postgresql-8.4-702.jdbc4.jar:. ExecSQL scriptfile

?

As best as I can vaguely guess from that tiny screenshot, to me it looks
like you're trying to open the JDBC driver jar and edit/view its source
code, but you haven't downloaded the source code so Eclipse can't find
it and is telling you so and providing a bytecode dump instead. If
that's the case, it's just a basic Eclipse usage issue - you need to
tell Eclipse where to find the source code.

Most JAR files do not contain the source code to the program. It's
distributed separately. See http://jdbc.postgresql.org.

Are you doing an Introduction to Java Programming course or something
like that? If so, getting you to use Eclipse probably qualifies as cruel
and unusual punishment - it's an expert's system and sometimes hard to
use even then. It's totally unsuitable for Java newbies. Check out BlueJ
(http://www.bluej.org/) or, if you need something a bit more capable
than that, look at the Netbeans IDE at http://netbeans.org/ .
