Learning JAVA and executing it

Damien360 · 19-05-2012 03:19PM #1

I have decided to try and pass a bit of time and learn a computer language. I have decided on Java and a bit of VBA for excel.

I found a site for java http://www.thanassis.com/java/java%20training%20course/introduction%20to%20java.html

but... I want to try the lessons out and figure it out myself. I downloaded the java 2 JRE from oracle but that just seems to be the usual java update. I tried using the console on chrome but when I enter anything I get "unexpected response....".

What do I need to download to write, compile and execute JAVA. The only programming I have ever done was BASIC (I was decent at that) many moons ago and a good stab at PASCAL but that is long gone from the brain now.

Any help appreciated.

(once I get started on JAVA I will tackle VBA)

Mods: If this is in wrong place, please move it.

You could download a sort of writer/compiler or do it this way.

Here is a quick vid on how to compile using Notepad++ (text editor).

I've jsut started studying for the java associate cert and my tutor recommends learning to compile and run from the command line as its good to learn the file paths etc.

Having said that we mainly use eclipse IDE..

I'd also recommend getting head first java as it has helped me no end.

Some sites I use for help are:
http://thenewboston.org/-> excellent video's and there s also 200+ on visual basics too

http://www.javaranch.com/java-college.jsp-> a decent java forum for all levels of expertise.Has helped me out(often by pointing out the obvious!:pac:)

You just need to download the Java Development Kit from here http://www.oracle.com/technetwork/java/javase/downloads/index.html

You just download the JDK that is the same version as your JRE.
You can check this in control panel or

from a command prompt type: java -version

If the first line says 1.6 then get the JDK were it says Java SE 6 Update 32
If it says 1.7 get JDK 7.

There's some good tutorials for Java on Oracle's website to start you off:

http://docs.oracle.com/javase/tutorial/index.html

Once JDK is installed you should be able to open a command prompt and run javac - it will print out usage information if all is working correctly.

Paths in MS-DOS are no bother as my computing experience started back on 486 machines and before windows.

I had a look at the helloworld starting point and came across the case sensitive malarchy very quickly. With that I think an IDE is a must.

I am downloading eclipse from filehippo as I type but looking at the screenshots, it may be a bit of a monster. What is the most prevelant IDE in use. I am thinking I may just learn one IDE only and stick with the most common one for support.

I had a scan of that and it starts right from scratch. A very nice resource complete with a downloadable pdf. It also explains some very basic questions I had concerning the hello world.

Thank you
