[adil zahir]

i want mak somme test for that i creat 2 class

package com.data.classeur;
import com.data.cour;
public class F {
 public static D d ;
 public static void main(String [] args ) {
      d = new D();
	  System.out.println(d.name);
	  d.f();
 }
 }

 package com.data.cour;

public class D {
    String name="adil";
	public void f(){
	System.out.println(" access defaul " );
	}
	
}

so for compile using command line

javac -cp /com/data/cour ; F.java

i have error i don't know why ?

[Sourav Sarker]

javac -cp /com/data/cour ; F.java

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 com.data.cour -d . com/data/classeur/F.java

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 :

root
|
com
|
data
|
----cour
| |
| D.java & D.class
|
-----classur
|
F.java & F.class



Commands from root directory:

javac -d . com/data/cour/D.java
javac -cp com.data.cour.D -d . com/data/classur/F.java

To run :

java -cp com.data.cour.D F



I think this will work..


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

import com.data.cour.D
