java.lang.ArrayIndexOutOfBoundsException: 0 >= 0 attempting to populate JTable

Question

I\'m subclassing JTable and using a DefaultTableModel to model my table data. The following class sets up the JTable, and adds one row to the model.

import          


        

Answer 1

I ran on this issue too (with a JList and a DefaultListModel). Dmitry's answer is right.

However, there is another thing: this exception can also be thrown if you don't modify the model in Swing's Event Dispatch Thread.

Doing the following can help you avoid this exception:

SwingUtilities.invokeLater(new Runnable(){public void run(){
    //Update the model here
}});
