cant use Command Prompt to run Java App (with screenshot)

[LongTTH]

Just HelloWorld "application" like this
the .java file is in C:\Examples\je3\basics

package je3.basics;                           
public class Hello {                         
    public static void main(String[  ] args) {  
        System.out.println("Hello World!"); 
    }                                       
}

when I jump into that folder and use javac to complie, it's OK.

but when I use java to run it:

even I've try changing the path to the .class file. It's still not OK

this is my java version and javac version:

My Environment Variables:
CLASSPATH and JAVA_HOME:

.;%JAVA_HOME%;

C:\Program Files\Java\jdk1.6.0_25

Path

-
event I can use Eclipse or other IDE to run it. I really do want to know how to do it (run my little HelloWorld app just with JDK and Command Prompt).

You've defined your class to be within a package, so compile and run the class(es) from the root of the package (eg cd up to the Examples directory, then javac (or java) the class from there je3/basics/Hello

... or alternatively, don't specify a package for the class; I don't recommend this option because you are going to meet the troubles of packages later again, but it is a quick fix/hack for now.

kind regards,
