java - New ArrayList with same values -

i have arraylist:

arraylist<integer> example = new arraylist<integer>(); example.add(1); example.add(1); example.add(2); example.add(3); example.add(3); 

so want make others 3 arraylists containing in 1 same values (where there 1 value arraylist have one).

is possible?

here's approach filtering out elements, implemented: using generic map (in generic class) encapsulate values.

• the key object want, , value determined follows:
  • if key never existed, have list @ 1 element, same key;
  • if key has existed prior, have list @ least 1 element, same key.

here's how it's laid out. instantiate type of object want split.

public class uniquesplitter<t> {      public map<t, list<t>> filteroutelements(final list<?> thecandidatelist) {         final map<t, list<t>> candidatemap = new hashmap<>();         for(object element : thecandidatelist) {             if(candidatemap.containskey(element)) {                 candidatemap.get(element).add((t) element);             } else {                 final list<t> elementlist = new arraylist<>();                 elementlist.add((t) element);                 candidatemap.put((t)element, elementlist);             }         }         return candidatemap;     } }
