Exception in thread "main" java.lang.NoClassDefFoundError: app

Hello! I loaded j2sdk_1.4.2_04 onto may machine and I wanted to test a simple hello program below.

// Hello Pogram

public class app

{

public static void main(String[] args)

{

System.out.println("Hello from Java!");

}

}

// End of Hello Program

When I run it by typeing

java app (note the file name is app.java)

I get the error "Exception in thread "main" java.lang.NoClassDefFoundError: app"

I checked various support pages and they mentioned the classpath not being set. So, I tried setting the class path to c:\j2sdk_1.4.2_04\bin;.;c:\j2sdk_1.4.2_04\lib but I still couldn't resolve the problem. I have the app.java in the c:\j2sdk_1.4.2_04\bin and this is also where I am running the java app command.

Thanks for your help,
