Name: aaC67449 Date: 08/18/99




The JTable(1, 0) constructor throws ArrayIndexOutOfBoundsException, but
should create a table with one row and no columns.

javadoc says:"
public JTable(int numRows,
              int numColumns)

      Constructs a JTable with numRows and numColumns of empty cells using
the
      DefaultTableModel. The columns will have names of the form "A", "B",
"C", etc.
      Parameters:
            numRows - the number of rows the table holds
            numColumns - the number of columns the table holds
      See Also:
            DefaultTableModel
"

See example.
------------- example --------------
import javax.swing.JTable;

public class Test {

   public static void main(String argv[]) {
       JTable c = new JTable (1,0);
   }

}
