java -cp c:\ ddd
you must leave a space between the path and the class file.

setting the classpath helps the java applications find the user defines classes.

By specifying java -cp/-classpath path classfile you r overiding the default classpath which is set.

If ddd is your class file then your command would be

java -cp . ddd "." specifies all the files in the current directory.

hope that helps
