I created another class which uses Vector to store the object like that:
How can I write vector object (name, sex and age for all objects) to a text file LINE by LINE? How can I cast that object's name, sex and age to be String? Thanks for help. Andrew

I think you mean how do you write what's IN the object to a text file, right? In this case you don't have to cast them to Strings, they are already Strings. If you mean a single step to return the instance variables as a single String, you could override the toString() method of X to put them all together in one String: In X...
Or something like that depending on your needs. Then you have a choice of whether you want to build a big String(delimited by newlines) and write it to the file all at once, or write once for each object in the Vector. Check out these links for writers: BufferedWriter FileWriter PrintWriter HTH, E
