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 was facing this problem because i was adding columns and rows to the JTable not to the model.

best way is this.

Object[][]rows = new Object[ ][ ] { {"a","b"} , {"c","d"} };
Object[]columns = new Object[] {"column1","column2"};
JTable table = new JTable();
table.setModel(new DefaultTableModel(rows,columns));
