How to set letter spacing in Java Swing GUI?

Question

In CSS, there is a letter-spacing property that we can use to increase spacing per letter in a word.

Is there a way I can increase a letter space or text space? I was hoping I can increase the space of the text in a field.

Answer 1

Here is an example:

public static void main(String[] args) {
    SwingUtilities.invokeLater(() -> {
        JLabel label = new JLabel("This is a text.");
        Map<TextAttribute, Object> attributes = new HashMap<TextAttribute, Object>();
        attributes.put(TextAttribute.TRACKING, 0.5);

        label.setFont(label.getFont().deriveFont(attributes));
        JOptionPane.showMessageDialog(null, label);
    });
}

Result:
