...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());

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.

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.

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.
