CODE
class vectorsprog
{      
         public static void main(string args[])
          {
            system.out.println("Enter 3 points in space which form a traingle.");
          }
}

C:\Java\jdk1.6.turn.gif6\bin>javac vectorsprog.java
vectorsprog.java:3: cannot find symbol

location: class vectorsprog
public static void main(string args[])
^
vectorsprog.java:5: package system does not exist
system.out.println("Enter 3 points in space which form a traingle.")

Java is a case sensitive language. Both "String" and "System.out.println" start with capital "S". Otherwise Java doesn't know what those words mean with the lowercase "s".

Also, while it is not crucial, you should specific "public" before the class name unless it is in a file with another class. You will see a lot of examples that show classes starting with the keyword "public" it is just good practice to make it explicit.

Fix those two capitalizations and you will have something that works. smile.gif

I recomment you use netbean for the compiler...

NetBean:
http://download.netbeans.org/netbeans/6.1/final/

I Free to download...

You use this compile then you will not type wrong code... Cheer

It would work with any IDE that automatically looks up symbols, not just NetBeans. But NetBeans is free, and has a GUI builder.

BTW, you can only make a class public if it has the same name as the source file. Also, there can only be one public class in a file, so if you plan to add another class to your source, you cannot make it public.
