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

From the JTable.setAutoCreateColumnsFromModel() API:

"This method calls createDefaultColumnsFromModel if autoCreateColumnsFromModel changes from false to true. "

Vector throws ArrayIndexOutOfBoundsException - if the index is out of range ( index < 0 || index >= size())

I guess the table model is missing the columns, as suggested by Dmitry

Answer 2

I think you need to add columns to your TableModel. Your code adds UI columns to the table but doesn't add them to the model

Answer 3

Replace your code with the following Here you need to remove first row only that should be iterated for all the rows

private void refreshTable() {

   int rowCount= model.getRowCount();

  // System.out.println(rowCount);

   for(int i=0;i<rowCount;i++ ){
        model.removeRow(0);
        //System.out.println(i);
   }

}

Answer 4

replace

tabWindow.addTab(...);

with

SwingUtilities.invokeLater(new Runnable() {
    @Override public void run() {
        tabWindow.addTab(...);
    }
});

Such situation can hapen when you change tabbed pane in action listener.

Answer 5

It is necessary to add isCellEditable method to your table model class with return false.

@Override
  public boolean isCellEditable(int row, int column)
  {
    return false;
  }

Answer 6

Dmitry is right. Replace

this.addColumn(ColumnName);
this.addColumn(ColumnSize);
this.addColumn(ColumnRmIcon);

with

Model.addColumn(ColumnName);
Model.addColumn(ColumnSize);
Model.addColumn(ColumnRmIcon);

and now the Model knows about the columsn and won't throw an Exception anymore when you try to add a row to a model which thinks it has 0 columns
