Java how to set the text of a jlabel to bold

To set the text of a JLabel to bold in Java, you can use the setFont method and pass it a new font object with the desired style.

Here's an example of how you can do this:

JLabel label = new JLabel("Text to display");
Font currentFont = label.getFont();
label.setFont(new Font(currentFont.getName(), Font.BOLD, currentFont.getSize()));

This will create a new Font object with the same name and size as the current font, but with the BOLD style applied. You can also use the ITALIC or PLAIN styles to set the font to italic or regular, respectively.

Alternatively, you can use the setBold method of the StyledDocument class to set the text of a JLabel to bold. This method is more flexible, as it allows you to apply different styles to different parts of the text within the label.

Here's an example of how you can use the setBold method:

JLabel label = new JLabel("Text to display");
StyledDocument doc = label.getStyledDocument();
SimpleAttributeSet bold = new SimpleAttributeSet();
StyleConstants.setBold(bold, true);
doc.setCharacterAttributes(0, doc.getLength(), bold, false);

This will set the text of the JLabel to bold, starting at the first character (index 0) and continuing to the end of the document.
