Private members and methods can be accessed by outer world using reflection concept in java.

Please have a look on http://www.onjava.com/pub/a/onjava/2003/11/12/reflection.html this link. This link gives the information about REFLECTION which can be used to access private methods and it is well explained.

Now my question is How to prevent reflection to access private methods and members in java classes?

You will need to use the security manager; see the Security Features in Java SE tutorial to start with. This is how applets are prevented from accessing local files, and from using reflection to get around these limits.

In particular, setAccessible(true) checks for ReflectPermission("suppressAccessChecks") before allowing access to private members.
 
I agree. Here's the link: http://aspose.com/file-tools
