java programm,

so, i readed some shit about java and i understand a bit, but i want to know how good i think i know about java so, could some1 give me a little nuby tutorial about how to make a programm in java

thanx,

What do you want to make? Hello world? Give me an idea and I can prbly explain it too you.

something little more difficult than hello world, just some aplication that is usefull for me
something like a .. i dont really know XD

, somehting like a chat.chat box or something?
something like msn that other ppl can join or somehting?

I think that would require a sever or something. Though I suppose you could code a servlet in Java, but you still need to designate a computer to host the traffic.

Maybe something simpler. Tell me what do you know so far and I can come up with something fun I think.

ok, like the hello world? nooby tutorial step by step if thats not to much for you XD

Ok. Here's a fun lil starting program. You'll have to forgive me for the lack of flare, but Im a lil rusty when it comes to Java, but I need to get back up to speed if I want to program Android. Anyway lets get started.

Lesson: 1

[php]
import javax.swing.JOptionPane; //we are importing the JOptionPane that will make the pretty window for us.

public class HelloName //the name of our class. Unlike C++ everything is a class. A class can be run directly only if it has a main method.
{

public static void main(String[] args) //the main method for all Java programs
{
//
JOptionPane.showMessageDialog(null, "Hello, World"); // the method showMessageDialog() is a static method called from the class JOptionPane
String name = JOptionPane.showInputDialog("what is your name?"); will save your answer into the String name.
JOptionPane.showMessageDialog(null, "Hello " + name);//Now we use String name to greet the user.
System.exit(0); //return 1; in C++ Basically we exit the program. And return control to the system.
}
}

[/php]

This a fun little Hello world program. You enter your name and it greets you.
I commented the code to explain what I can, but feel free to ask questions.

Now since I pretty much gave you the code you should do something with it to be sure you understand it. I want you to create a program that will ask for a persons name and age and then greet the person with both.

EDIT: Oh yeah one more thing... man its been a while since I've done java. I'm a little out of it. Anyway was gonna say that System.exit(0); really isn't needed since Java automatically handles that usually, but you can put it anyway. You can also just put return; too... it doesn't matter in this case.

so i think;

i copy&past this(lol) to notepad and i save as helloworld.java and than?>>>?
XD this is just a try for me to go realy studiing on java

Notepad?
Well I would get urself a Java IDE. Unless ur good at cmd line which im not.

I think "java projectfoldername.class" will compile it, but idk. I suk @ command Im prbly 90% wrong, and you would still need to set the classpath.

Just get a compiler like BlueJ or Eclipse.
