How to save an int to a file and then read it back in android

Question

I am creating an app and I'm still very new to programming. I was looking around for a long time to find out, how to save an int to a file and then read it back later, but I found nothing. Here's the snippet:

int Money = 750;
Save.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
    }
});

So when the button is pushed, the int should be saved to a file called Money.txt .
