Question

I wrote a program on moving data from one list to another using JList. But when I move the selected data from one list to another, the previous enteries in the list to which I moving data gets overwritten by the new data.

How can I make program in which the previous enteries I made in a list doesn’t get overwritten by the new data which I try to move?

Regards

Whenever adding an element to the list, you should add it to the list model using methods like addElement().

Don’t add data to the JList using setData() or similar methods.

DefaultListModel model = new DefaultListModel();
JList list = new JList(model);
model.addElement(someElement);
