How to add JCheckBox in JTable

In this tutorial, we are going to see how to add JCheckBox in JTable. 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 in a JTable, a TableModelEvent is generated, which is handled by implementing a TableModelListener interface. We can add or insert a checkbox in a JTable cell by implementing the method getColumnClass().

We need to redefine the method getColumnClass() to return Boolean.class for the appropriate column.

Java Program to add JCheckBox in JTable:
import javax.swing.*;
import java.awt.*;
import javax.swing.table.DefaultTableModel;

public class CheckBoxInTable extends JFrame 
  public CheckBoxInTable() 
    //Headers for JTable
    String[] columns = {"Id", "Name", "Address", "Available"};

    //data for JTable in a 2D table
    Object[][] data = {
      {1, "Thomas", "Alaska", true },
      {2, "Jean", "Arizona", true },
      {3, "Yohan", "California", false },
      {4, "Emily", "Florida", false }

    DefaultTableModel model = new DefaultTableModel(data, columns);

    JTable table = new JTable(model) {
      public Class getColumnClass(int column) {
        //return Boolean.class
        return getValueAt(0, column).getClass(); 

    JScrollPane scrollPane = new JScrollPane(table);

    JLabel labelHead = new JLabel("List of employees");
    labelHead.setFont(new Font("Arial",Font.TRUETYPE_FONT,20));

  public static void main(String[] args) 
    CheckBoxInTable frame = new CheckBoxInTable();  
    frame.setSize(400, 200);
