How to create DefaultTableModel which is an implementation of TableModel

Java 8 Object Oriented Programming Programming

Let us create DefaultTableModel −

DefaultTableModel tableModel = new DefaultTableModel();

Now, set the model to JTable −

JTable table = new JTable(tableModel);

Add a column −

tableModel.addColumn("Languages");

Now, we will add rows to our table −

tableModel.insertRow(0, new Object[] { "CSS" });
tableModel.insertRow(0, new Object[] { "HTML5" });

The following is an example to create DefaultTableModel −

Example

package my;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
   public static void main(String[] argv) throws Exception {
      DefaultTableModel tableModel = new DefaultTableModel();
      JTable table = new JTable(tableModel);
      tableModel.addColumn("Languages");
      tableModel.insertRow(0, new Object[] { "CSS" });
      tableModel.insertRow(0, new Object[] { "HTML5" });
      tableModel.insertRow(0, new Object[] { "JavaScript" });
      tableModel.insertRow(0, new Object[] { "jQuery" });
      tableModel.insertRow(0, new Object[] { "AngularJS" });
      tableModel.insertRow(tableModel.getRowCount(), new Object[] { "ExpressJS" });
      JFrame f = new JFrame();
      f.setSize(550, 350);
      f.add(new JScrollPane(table));
      f.setVisible(true);
   }
}
