javac -cp /com/data/cour ;

If you are using windows OS, First skip the First '/' because it is used in solaris for the root folder. and skip the ';' . Instead of semicolon (;) use a single space...
I think it will work fine ...

-cp or -classpath works for same . As an example. After the -cp tag you must specify the fully qualified name of the class.
So use

javac -cp -d . com/data/classeur/

from root of com folder. -d . means where you want to save the class files...
[ simply to understand : -cp is followed by a fully classified class path and -d is followed by a directory location to store class]

Pictorially Example :

| |
| & D.class
| & F.class

Commands from root directory:

javac -d . com/data/cour/
javac -cp -d . com/data/classur/

To run :

java -cp F

I think this will work..

Oh check your code... You just import package not package Class
change that into

I am so sorry for that . I was in so much hurry when i was writing it. So It was skipped and i did not see that. Alam Ameghino
Consider you code :

public static void m1(Dog... ds) {
for (Dog d : ds)
d = null;

public static void m2(Dog[] ds) {
for (int i = 0; i < ds.length; i++)
ds[i] = null;

these m1() amd m2 methods are different because of it's for loop... Just see ... what happened for m1() method....
forEach loop : firstly initiates the variable d and then chage the value d to null;
so it's it like this :

a=5; b=a; b=0;

So, will the value of a change ?
of course not...

For the second m2():
for loop is working with the index (i) and assigning null to the arrays all position... So it changes....

These are the difference between ... so they are not same....

Which two are true? (Choose two.)
A. An encapsulated, public class promotes re-use.
B. Classes that share the same interface are always tightly encapsulated.
C. An encapsulated class allows subclasses to overload methods, but does NOT allow overriding methods.
D. An encapsulated class allows a programmer to change an implementation without affecting outside code.
