or you can just download the lib needed and use any editor and then javac your file, you will also have to edit your $path

Slackware 10.2 comes with a version of the JDK (and JRE for that matter). You can install them from your CDs, or get them from these links:

You could also try an integrated development environment like Borland JBuilder or Eclipse. Both are free. I use JBuilder. It checks for errors as you go and is very straightforward to use as a programming environment. Eclipse is supposed to be very good but I have no experience with it.

The only problem I have found in JBuilder is that it defaults to using visual gui development. Fine if you want it but if you don't it is possible to circumvent it.

Thanks for all.
I am new you know. How can i compile java sources?
For example i have a source file like this :

Code:

Welcome1 {
	main(String args[])
	{
		System.out.println("Hello world");
	}
Welcome1 {
	main(String args[])
	{
		System.out.println("Hello world");
	}
}

I think i have to compile like this :

Code:

bash-3.00$ javac welcome.java
welcome.java:1: 'class' or 'interface' expected
Welcome1 {
^
1 error

But as you see i get a error i dont know why?

You are missing the class or interface keyword:

Code:

public class Welcome1
{
   public static void main(String[] args)
   {
       System.out.println("Hello World!");
   }
}

Edit: also, your source file must have the same name as your class, so for the example above, your file should be called Welcome1.java.

It's real nice and it helped me a lot when I was learning off Java
