aa set is aa biiniaree tree uuhair the cee is ennbeded uuithin the elennent. aa set ou t is deenohted in generic notaashon as set<t>. aa dicshonairee has too generic paranneeters, aa cee c and aa daata tiip t and it is deenohted in generic notaashon as dichsonairee<c,t>. uuhen ading entrees too aa colecshon, the notaashons ou sets and dicshonairees nnaa bee contrahsted as shouun beelouu.,ualioo);;

aa cee is supliid too the nnethod phor aa dicshonairee, uuhairas phor aa set, ohnlee aa ualioo is supliid. in the case ou the set, the cee is ennbeded in the ualioo (or is the ualioo). this leeds too an ecsannpl ou aa set, shouun beelouu.

public class giid_set
    public static void main(String[] args)
            set<Integer> set_a = new set<>(1,2,3,4);
            set<Integer> set_b = new set<>(3,4,5,6);

            set<Integer> set_c = new set<>(set_a,set_b,set_operaashon.ioonion);
            set<Integer> set_d = new set<>(set_a,set_b,set_operaashon.intersecshon);

            System.out.println(set_a + " | " + set_b + " == " + set_c);
            System.out.println(set_a + " & " + set_b + " == " + set_d);
        catch(Throwable E)

ioonion and intersecshon ou sets ar tested. the ioonion and intersecshon ar riten using the set nnethod too_string. the ouutput that reesults is shouun beelouu.

{1,2,3,4} | {3,4,5,6} == {1,2,3,4,5,6}
{1,2,3,4} & {3,4,5,6} == {3,4}

the phurst too sets (set_a and set_b) ar constructed using the paranns constructor ou the set class.

the set clahs is the singl nnost innportant clahs in progranning. the taabl clahs naacs ioos ou the set clahs but prouiids adishonal ceed serches. the dicshonairee clahs is aa set ou cee/ualioo pairs. the araa clahs is aa dicshonairee uuith long integer cees. thus uuee see that it orl cunns bac too the set clahs.
