Hello! I'm a new Eclipse user. I have some little knowledge about
programming in JAVA. I was using the GEL IDE for JAVA. Now i found the
ECLIPSE!
I want to know one thing:
In gel when I write the constructor method, when I open the first
parenthesis, the IDE give's me the parameters details for that
constructor. But in the ECLIPSE nothing like that occurs. Is there any
function I can activate for this to happen?

It's a little hard to describe. On my system, I get a yellow box next to
the list of options. For example, if I type "sys" and then press
CTRL-Space, I get a list of options. If I arrow down to "System -
Java.lang", I get a yellow text box next to the drop-down list box that
contains a bunch of documentation about the System class. As I arrow up or
down, the text in the box changes.
By the way, if you do a lot of System.out.println("test") commands, a cool
shortcut is to just type in the string you want to print (e.g., "test"),
highlight it, press CTRL-Space, the UP arrow, and ENTER. Eclipse puts in
the rest of the command automatically. CTRL-Space is your friend! HTH.

Thanks again Mark Dexter! I have found the solution for my problem!
The Eclipse detected the JRE in my machine and not the JDK. So, the JRE
was unable to give the documentation about the methods and parammeters. So
I did a search and selected the JDK path and enabled it. Thats all!
Now when I type "sys" and then press CTRL-Space, I get a list of options
and a yellow text box next to the drop-down list box as you said.
But for one thing I am not really happy. I can't read all the
documentation in the yellow box. It's too small! I think a good ideia
would be to have a scroll bar under the box so we could read all the
information it gives.

At the bottom of the yellow box, it says "Press F2 for focus". If you do
that, you can scroll the text box. Cheers. Mark Dexter
