Writes binary right handed and hex left handed

Ok I am trying to start Java, my friend told me to install the JDK and BlueJ.. But now I have no idea what to do! Where can I find some tutorials.. and after making a program how do I run it? only from the Command Promt? Isn't it possible to make a windowed (GUI) application?

Thanks!

A good start would be to read the official BlueJ tutorial.

I tried to read that, but it took me to nowhere... but I found a tutorial to make a java applet and write hello.. it is quite complicated.

You can create GUI's but Swing is known to be a bit of a pig when it comes to syntax and there are all sorts of gotchas about threads and that. It really is easier to learn from the CLI in my experience. Just far simpler to create a program that takes arguments from args[].

Take a simple example like fib. You could do something like 'java fib 10' from the CLI to basically test a program outputting fib(10). This can be coded in about a line or two. Doing a GUI for this would take a huge assortment of code. Even a GUI editor would take much longer.
