Question

I need to define an attribute like
Long district
And this district attribute need to contain more than 10 values And each value's value update or increase count

Answer 1

write a class if values are of different types
class District {

if there are values of same type and purpose use an array
int[] num = new int[10];
or
var data = new ArrayList<Type1>();
