Question

Helo. I have two arraylist’s:

public static ArrayList<Shop> shops;

with field: public static double dist;

and the second arraylist: public static ArrayList<Double> for_sort_shops;

I also have a code:

for (int i = 0; i < shops.size(); i++) {
    Log.i("palval", "for_sort_shops.get(i) = "
            + for_sort_shops.get(i));
}

for (int i = 0; i < shops.size(); i++) {
    shops.get(i).dist = for_sort_shops.get(i);
}

Log.i("palval", "---------------------------------------");
for (int i = 0; i < shops.size(); i++) {
    Log.i("palval", "shops.get(i).dist = "
            + shops.get(i).dist);
}

And what result I’ve get?

How it’s possible?!
Help me to understand.

Answer 1

You declared dist static, which means that it’s value is defined at class level and shared among all instances. in your program you only see the last value assigned to it.
