עזרה ב JAVA עם עורך JCreator

[Hanan]

אהלן חברים,
התחלתי בזמן האחרון ללמוד שפת JAVA עם העורך JCreator.

משומה שאני מריץ תוכנית בסיסית לדוגמה:

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

ותמיד זה מביא לי שגיאה:

--------------------Configuration: default - JDK version 1.6.0 <Default> - <Default>--------------------
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)

where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.

-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A ; separated list of directories, JAR archives,
and ZIP archives to search for class files.

-verbose[:class|gc|jni]

-version print product version and exit
-version:<value>

-agentlib:<libname>[=<options>]
