how to get subsets of specific number from a given set of numbers?

Question

there can be n number of subset from set, also where to save that subset.

Answer 1

create an empty collection.
Iterate over the numbers, make a condftion for the specific number(s) and in the if add the current number to the created collection.

Example:
Lets numbers contains {1,2,3,4,5,6}
List<Integer> evenNumbers = new ArrayList<>();
for(Integer i : numbers){
if(i % 2 == 0){
evenNumbers.add(i);
}
}

Then evenNumberscontains {2,4,6}

It works for Set too instead List.

Hi !
You must create a powerSet first, then you can get the subset from that.
