Java Swing not working...

I'm a beginner to Java and was trying to complete a Swing tutorial.  I entered the code and ran it, but did not get the pop up window as the tutorial suggested i would.

Not sure what's not included in my code or files.  I don't have any errors showing up in Eclipse.  I have one warning: The serializable class Simple does not declare a static final serialVersionUID field of type long - but i don't think that's the problem.  When I run the code I get the following in the Console area of the Eclipse IDE:


Usage: javaw [-options] class [args...]
           (to execute a class)
   or  javaw [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -server        to select the "server" VM
    -hotspot        is a synonym for the "server" VM  [deprecated]
                  The default VM is server.
                 
    -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.
    -D<name>=<value>
                  set a system property
    -verbose[:class|gc|jni]
                  enable verbose output
    -version      print product version and exit
    -version:<value>
                  require the specified version to run
    -showversion  print product version and continue
    -jre-restrict-search | -jre-no-restrict-search
                  include/exclude user private JREs in the version search
    -? -help      print this help message
    -X            print help on non-standard options
    -ea[:<packagename>...|:<classname>]
    -enableassertions[:<packagename>...|:<classname>]
                  enable assertions
    -da[:<packagename>...|:<classname>]
    -disableassertions[:<packagename>...|:<classname>]
                  disable assertions
    -esa | -enablesystemassertions
                  enable system assertions
    -dsa | -disablesystemassertions
                  disable system assertions
    -agentlib:<libname>[=<options>]
                  load native agent library <libname>, e.g. -agentlib:hprof
                    see also, -agentlib:jdwp=help and -agentlib:hprof=help
    -agentpath:<pathname>[=<options>]
                  load native agent library by full pathname
    -javaagent:<jarpath>[=<options>]
                  load Java programming language agent, see java.lang.instrument
    -splash:<imagepath>
                  show splash screen with specified image


I've attached my code below.  Any help would be appreciated!  Thanks!

package jSwing;

import javax.swing.JFrame;


public class Simple extends JFrame {

    public Simple() {

        setSize(300, 200);
        setTitle("Simple");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
   }

    public static void main(String[] args) {

        Simple simple = new Simple();
        simple.setVisible(true);

    } 
}
