I have installed the NetBeans IDE. Now I want to start to do something. But I do not understand the idea of the “project”. I know that I can have source files, then I can compile them and execute. But what does the project mean?
OK. I wanted to figure out that by opening a “New Project”. But when I start it I need to select between the “Java Application”, “Java Desktop Application”, “Java Class Library” and so on. I have no idea what it means.
I just want to write a program which does certain things (track keyboard activity). How should I classify it? Java Application? Java Desktop Application? Something else?
Go straight to Java Application. Java Desktop Application will make you learn a framework which is unnecesary at this point of your learning curve.
If you want to do a simple example, take a look here: http://netbeans.org/kb/docs/java/javase-intro.html or the more general http://netbeans.org/kb/trails/java-se.html
Keep on working it, man.
