+1 Is this characteristic of the
DefaultTableModel?
mKorbel
yes or no too, I never see some differencie between set Array/Vector, to the myTable (data[][], header[]) or standard way to stick Abstract/DefaultTableModel, by permormance issue (my view) I'm not fans for Set or List family wraped into TableModel, +1 :-)
Java supports multi-dimensional data structures such as List<List<…>>. ArrayList is just one implementation of the List interface, and each dimensions may use a different implementation. This example illustrates List<List<Integer>>.
The two dimensional case may require nothing more elaborate than List<Record>, shown here; or List<Value>, shown here in the context of an AbstractTableModel. See Creating a Table Model for additional details.

ArrayList<String > arl = new ArrayList<String >();.....Object obj = arl.clone();.... final JTable table = new JTable(data, obj); give an error
...is there 2 dimensional arraylist in java... - Yes
// T is the type of your data.
List<ArrayList<T>> list = new ArrayList<ArrayList<T>>();
UPDATE
To use the data from the ArrayList in the JList you need to convert it to an array of objects. For example:
JList jlist = new JList(list.toArray());
how to bind it in listview
JList has a AbstractListModel that works a lot like how JTable has a AbstractTableModel. If that's what you want, the examples in "How to Use Lists" may help.

I don't know what a "listview" is. But if you want to display data from an ArrayList in a JTable then you need to create a custom TableModel. List Table Model is one implementation that you can use.
