i have data in format
list<object[]> data = new arraylist<object[]>(); for(something s : somelist) { object[] templist = { s.test, s.test2, s.test3 }; data.add(templist); } so have arraylist of objects[]. want arraylist of objects object[][] have data in format
object[][] data = { { test, test2, test3 }, { test4, test5, test6 } }; but i'm not sure how that.
the arraylist step isn't important, it's direction took when trying figure out. if have better way of getting data object[][] that's great.
you can use list#toarray(t[]):
object[][] array = data.toarray(new object[data.size()][]);
