Sorting Dates - Saving Result In Class

So, I have two classes (bubble sort and insert sort) which are sorting dates. I need to save their comparings and reallocation of elements.

And I don't know how to do it. The point is if I want save that dates(comparings and reallocation) to Result class i need to create new instances of class in each sorting classes so i can't later do something with that, because I have null in Main class.

To avoid that problem i have tried to make Result class as singleton.. I mean: "public static final Results INSTANCE = new Results();" and then in classes "static Results result = Results.INSTANCE" without constructor and to save for example comparings i had method:

Java Code:

int SetComparings(){
return comparings++;
} mh_sh_highlight_all('java');

But it do not work too, because it overwrites old dates. Is there anyway to do not create instance of class? I don't want to copy whole code because it is too long and cant be unreadable, but i will put you structure of my program:

Java Code:

class BubbleSort{}
class InsertSort{}
class Results{}
class Sorting{} // class with switch to choose which way of sorting use
public class Main{} mh_sh_highlight_all('java');
