Hello,

I'm wondering if Java has the ability to save a Hashtable and be used by other programs.

Would it be possible to save the hashtable to a disk?

I guess this would be like PERL's DBM files.

thanks,

-Mike

Thank You for the help.

I serialized the Hashtable and this does what I need to do.

Assuming the contents of the Hashtable are serializable, you can serialize the Hashtable.

Mike,

Not directly, but through the Serializable interface. Hashtable, like other classes that belongs to the Collecion API, implements the Serializable interface.

If the objects you insert inside the Hashtable implements the Serializable interface, you should be able to achieve your goal.
