Java implementation of the list to go heavy

Method One, use the For loop traversal to remove the repeating element code in the list as follows

 Public Static voidMain (string[] args) {Test07 test07=NewTest07 ();    System.out.println (Test07.getlist ()); }     PublicList getList () {list originallist=NewArrayList (); Originallist.add (1); Originallist.add (3); Originallist.add (3); Originallist.add (5); Originallist.add (7); Originallist.add (7); Originallist.add (13); List templist=NewArrayList ();  for(Object object:originallist) {if(!Templist.contains (object))            {Templist.add (object); }        }        returntemplist; }

Mode two, use set to redo the code snippet as follows

// The use of set set uniqueness to remove weight        New HashSet (originallist);         New ArrayList (set);         return templist;

Method three, using TreeSet to remove duplicate elements

New TreeSet (originallist);         New ArrayList ();        Templist.addall (TreeSet);         return templist;
