help needed in saving objects

hi to all,I don't know its is possible or not ,I want to save objects permanently[not in database] until i deleted it.I am keeping my data in a hash table to store sensitive information and i need the same data next time even the application was closed suddenly because of unexpected reasons,of course at last this information was saved in database.If it is possible pls help me.

you need to use ObjectStreams to write/read the data to/from a file.

Use FileStreams wrapped with ObjectStreams. Also, you need to ensure that your classes or their superclasses implement Serializable. If an application is closed suddenly, there is not much you can do about it, but other than that, you can write your objects to files

This is much better.

Actually it's not a good practice to keep lots of data in the memory. Better to write them into a file or a database.
