How to make JTable single selectable in Java?

To make JTable single selectable in Java, you need to set the selection mode to be SINGE_SELECTION. Let’s say the following is our table −

String[][] rec = {    { "001", "Shirts", "40" },    { "002", "Trousers", "250" },    { "003", "Jeans", "25" },    { "004", "Applicances", "90" },    { "005", "Mobile Phones", "200" },    { "006", "Hard Disk", "150" }, }; String[] header = { "ID", "Product", "Quantity" }; JTable table = new JTable(rec, header);

Set the selection more to make it single selectable with setSelectionMode() method −

table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

Let us see an example to set the same for our table in Java −

Example

package my; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.ListSelectionModel; import javax.swing.border.TitledBorder; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame();       JPanel panel = new JPanel();       panel.setBorder(BorderFactory.createTitledBorder(          BorderFactory.createEtchedBorder(), "Stock", TitledBorder.CENTER, TitledBorder.TOP));       String[][] rec = {          { "001", "Shirts", "40" },          { "002", "Trousers", "250" },          { "003", "Jeans", "25" },          { "004", "Applicances", "90" },          { "005", "Mobile Phones", "200" },          { "006", "Hard Disk", "150" },       };       String[] header = { "ID", "Product", "Quantity" };       JTable table = new JTable(rec, header);       table.setShowHorizontalLines(true);       table.setGridColor(Color.blue);       // make table single selectable       table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);       panel.add(new JScrollPane(table));       frame.add(panel);       frame.setSize(550, 400);       frame.setVisible(true);    } }
