How to Achieve Exclusive Selection in a JTable Using JRadioButton Groups?

How to Add JRadioButton to Group in JTable

Introduction:

Grouping JRadioButtons in a JTable ensures that only one button can be selected at a time, offering exclusive selection options within each row.

Original Approach and Associated Code:

The provided code employs renderer and editor classes to add JRadioButtons to a JTable and create groups for them. However, this approach alone is insufficient to achieve exclusive selection.

Alternative Approach:

As an alternative to JRadioButtons, consider using a JComboBox as an editor for mutually exclusive choices within a row. This method not only provides the desired functionality but also optimizes horizontal space utilization in the row.

Code Example:

// ... (Existing code)

// Replace RadioButtonRenderer and RadioButtonEditor classes with the following:

import javax.swing.JComboBox;
import javax.swing.table.TableCellEditor;
import javax.swing.table.TableCellRenderer;

public class StatusRenderer extends JComboBox<Status> implements TableCellRenderer {

    // ... (Existing code)
}

public class StatusEditor extends JComboBox<Status> implements TableCellEditor {

    // ... (Existing code)
}

// ... (Remaining code)

Explanation:

The JComboBox editor and renderer provide a user-friendly dropdown menu with the available Status options (Single, Married, Divorced). This eliminates the need for a separate button group and ensures exclusive selection.
