Saving vectors to files Posted: Dec 13, 2002 2:08 AM

I am trying to pass a vector of objects into a file in order to create a database that can be saved after each visit. However I am having problems getting the Output Stream to read the vector to the file. I have tried sending in the vector whole. Sending in each object individually and passing the objects into an array and then sending this in. The program compiles fine but when I run it and try to save to the file it crashes and gives me a number of error messages. Only one refers to a line in the program. This is where i try to write to the file.
Help!!!!!!!!

You said Output Stream, so I assume you are referring to OutputStream. I think if you use an ObjectOutputStream and all the objects in your collection are Serializable, you should achieve the effect you desire.
