Add the folder to the class-path.

>> package cde ;
If it is in a package, then add only its parent directory to the class-path.

> do i do like..import abc/abc.java?
use:
import abc.abc;
use:
import abc.abc;
>> Use: import abc ; for importing it
Sorry, that should have been:
import abc.* ; // for all classes
or import abc.abc ; // only for this class.

use:package cde;
in your abc.javafile
so that u can access that java file
try it

abc
| - abc.java
after you compiled it (javac -d . abc.java), result will be
abc
| - abc.java
| - abc
| - abc.class
and also for cde.java
cde
| - cde.java
| - cde
| - cde.class
To import abc class into cde.java, you need to compile abc.java first (javac -d . abc.java)
, then add <abs path>\abc (that contains abc.java) directory into your classpath (as mayankeagle commented)
, and then compile cde.java.
>cde folder - contains cde.java labelled package cde

No way. He wants it to be in another package abc.
jtcy,
You asked the same question at:

- please don't ask the same question twice - that too, with the same subject! Since that one is closed, I'm expecting this one to be closed too. Or if you have any more doubts, then please ask them on THIS page since this is still open, and not on that page.

I hope you have given notice to my previous comment:
>> - abc folder should contain abc.class
>> - cde folder should contain cde.class
- Mind it. Its .CLASS file and not .JAVA file
>> Set the classpath till the parent directory of these two
- keep in mind like gnoon suggested that the parent directory need not be the same. In that case, you have to add both the parent directories to the class-path

Sorry, i didnt want to open two questions. I accidentally clicked twice of it. tats why. um~~~ regarding to this problem i donno`~ basically, i just want to go for a coke..but cant. lol
um.....Okay, as what i have said above.........I have:
folder ast - containing ast classes files, each are packaged as ast;
folder rclast - containing rclast classes files, each packaged rclast;
both folders exists in myDirectory.
NOW, the thing is I want to use ast classes stuff in rclast classes, but i was told to do this without changing anything of classpath.

Why would you want to do that without class-path? Did your teacher not tell you what classpath is?
It is very vital to Java: http://www.mindprod.com/jgloss/classpath.html
What you can try is: put your ast and rclast folders (containing the class-files) in the jdk\bin folder. See if that helps.
