How to create a Default Cell Editor that uses a JCheckBox in Java?

Java 8Object Oriented ProgrammingProgramming

Create a check box first and set value

JCheckBox checkBox = new JCheckBox("In-Stock");

Set the JCheckBox for the editor so that the editor uses the check box −

TreeCellEditor editor = new DefaultCellEditor(comboBox);
tree.setEditable(true);
tree.setCellEditor(editor);

The following is an example to create a Default Cell Editor that uses a JCheckBox −

Example

package my;
import javax.swing.DefaultCellEditor;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JTree;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.TreeCellEditor;
public class SwingDemo {
   public static void main(String[] args) throws Exception {
      JFrame frame = new JFrame("Demo");
      DefaultMutableTreeNode node = new DefaultMutableTreeNode("Products");
      DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Clothing");
      DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Electronics");
      DefaultMutableTreeNode node3 = new DefaultMutableTreeNode("Home Decor");
      DefaultMutableTreeNode node4 = new DefaultMutableTreeNode("Furniture");
      node.add(node1);
      node.add(node2);
      node.add(node3);
      node.add(node4);
      DefaultMutableTreeNode one = new DefaultMutableTreeNode("Shirt");
      DefaultMutableTreeNode two = new DefaultMutableTreeNode("Trousers");
      DefaultMutableTreeNode three = new DefaultMutableTreeNode("Jeans");
      DefaultMutableTreeNode four = new DefaultMutableTreeNode("Mobiles");
      DefaultMutableTreeNode five = new DefaultMutableTreeNode("Camera");
      DefaultMutableTreeNode six = new DefaultMutableTreeNode("Tablet");
      DefaultMutableTreeNode seven = new DefaultMutableTreeNode("Paintings");
      DefaultMutableTreeNode eight = new DefaultMutableTreeNode("Showpieces");
      DefaultMutableTreeNode nine = new DefaultMutableTreeNode("Wardrobes");
      DefaultMutableTreeNode ten = new DefaultMutableTreeNode("Bean Bags");
      node1.add(one);
      node1.add(two);
      node1.add(three);
      node2.add(four);
      node2.add(five);
      node2.add(six);
      node3.add(seven);
      node3.add(eight);
      node4.add(nine);
      node4.add(ten);
      JTree tree = new JTree(node);
      for (int i = 0; i < tree.getRowCount(); i++) {
         tree.expandRow(i);
      }
      tree.putClientProperty("JTree.lineStyle", "Angled");
      JCheckBox checkBox = new JCheckBox("In-Stock");
      TreeCellEditor editor = new DefaultCellEditor(checkBox);
      tree.setEditable(true);
      tree.setCellEditor(editor);
      tree.setRowHeight(25);
      frame.add(tree);
      frame.setSize(600,450);
      frame.setVisible(true);
   }
}

The output is as follows displaying CheckBox −
