    Question need help with saving data

    How can I save data from previos runs?
    I need to save the data of object "player" that has the fields:
    String name
    int health
    int strength
    int speed
    I might create more fields

    p.s. I'm a beginner, so please make it as simple as possible

    I need to save the data of object "player" that has the fields:
    Where do you want to save the data? In what format? How will you retrieve that data later?
    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?

    Look at the ObjectOutputStream for a way to write the contents of an object. And ObjectInputStream to read it back.

    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.
