When I try to run my program this is all I get (In red font):

Usage: javaw [-options] class [args...]
(to execute a class)
or javaw [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-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>

This forum is for Eclipse questions. For Java questions, I'd suggest
javaranch.com, jguru.com or stackoverflow.com.

I apologize, it appeared to be command line output from Java. You mean
to say that you right-clicked your Java class and chose Run As -> Java
Application?

Or, are you trying to run Eclipse (rather than "your program") and this
is what you're seeing?

If this is the case, then you'll want to read:

As far as that goes, here's something that's going to be very useful to
you in any forum:

This is a forum, not an instant message chat. Less than one hour isn't long enough to wait for a response. Your original question showed us the result, but said nothing of what you did to get it. Most of us aren't psychic. As Russell mentioned, asking complete questions will get you better answers.
