Re: need help with saving data
Where do you want to save the data? In what format? How will you retrieve that data later?I need to save the data of object "player" that has the fields:
For example:
If you write the data to a file, do you want the contents of the file to be text or can some of it be binary?
Re: need help with saving data
I'm not sure.
is there some sort of code that cant automatically create a file that saves the data and one that automatically retrives it?

Re: need help with saving data
Look at the ObjectOutputStream for a way to write the contents of an object. And ObjectInputStream to read it back.
Re: need help with saving data
I am not sure, but can the serialization help in this case?
Re: need help with saving data
The easiest way for beginners to do this would be to output all the objects to a text file before the program closes.
Since your Player class only has 3 attributes, that would be relatively easy to store.
Google "How to read/write to a text file java" and you will find many examples on how to do this.
What that will do is write those 3 attributes to a text file then when your program opens up again, it will read from that same file.
