Running this from command line in Java

I cannot run the following program from command line the usual way:

package animal_package;

public class my_animal {

    public static void main(String[] args) {

        System.out.println("Hello animal");
    }
}

E.g. from Command prompt: I go to "D:\Java\src\animal_package" where my java program is and compile it:

D:\Java\src\animal_package>javac my_animal.java  
D:\Java\src\animal_package>java my_animal  
Error: Could not find or load main class my_animal.java

I have looked on Google and came around class path problem but couldn't make any sense from it all.

Which command line would be correct in my case?

You can compile the class either from src directory using: javac animal_package\my_animal.java OR from animal_package directory using: javac my_animal.java

To run the program from src directory use java animal_package.my_animal OR java -cp . animal_package.my_animal

cd .. then java -cp . animal_package.my_animal. The package is part of the fully qualified class name. Or,

java -cp .. animal_package.my_animal
