Java Program to create DefaultTableModel from two dimensional array
The DefaultTableModel is an implementation of TableModel that uses a Vector of Vectors to store the cell value objects. At first create a two dimensional array for rows and columns −
DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
{ "India", "Asia" }, { "Canada", "North America" }, { "Singapore", "Asia" },
{ "Malaysia", "Asia" }, { "Philippins", "Asia" }, { "Oman", "Asia" },
{ "Germany", "Europe" }, { "France", "Europe" }
},
new Object[] { "Country", "Continent" });Above, “Country” and “Continent” are the columns. Now, set the above set of rows and columns to JTable −
JTable table = new JTable(tableModel);
The following is an example to create DefaultTableModel from two dimensional array −
Example
package my;
import java.awt.Font;
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(new Object[][] {
{ "India", "Asia" }, { "Canada", "North America" }, { "Singapore", "Asia" },
{ "Malaysia", "Asia" }, { "Philippins", "Asia" }, { "Oman", "Asia" },
{ "Germany", "Europe" }, { "France", "Europe" }
},
new Object[] { "Country", "Continent" });
JTable table = new JTable(tableModel);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}Output
