How to display "No records available" text in a JTable in Java?
A JTable is a subclass of JComponent class and it can be used to create a table with information displayed in multiple rows and columns. When a value is selected from a JTable, a TableModelEvent is generated, which is handled by implementing a TableModelListener interface.
In the below program, we can display "No records available" text if the rows are not available in a JTable.
Example
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class NoRecordTableTest extends JFrame {
private JPanel panel;
private JTable table;
private JScrollPane scrollPane;
public NoRecordTableTest() {
panel = new JPanel();
panel.setLayout(new BorderLayout());
String columnNames[] = {"Column 1", "Column 2", "Column 3"};
String dataValues[][] = {};
table = new JTable(dataValues, columnNames);
JLabel label = new JLabel("No records available");
label.setSize(label.getPreferredSize());
table.add(label);
table.setFillsViewportHeight(true);
scrollPane = new JScrollPane(table);
panel.add(scrollPane, BorderLayout.CENTER);
panel.add(new Label("No records available"), BorderLayout.SOUTH);
add(panel);
setSize(400, 300);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main( String args[] ) {
new NoRecordTableTest();
}
}Output
