alguem pode me dizer pq esse código:

... BasicDynaClass dynaClass = new BasicDynaClass("tester", null, null); java.util.List<DynaBean> ls = new ArrayList<DynaBean>(); while (param.hasMoreTokens()) { DynaBean db = dynaClass.newInstance(); db.set("campo1", param.nextToken()); db.set("campo2", param.nextToken()); db.set("campo3", param.nextToken()); db.set("campo4", param.nextToken()); db.set("campo5", param.nextToken()); ls.add(db); } ...
