How to display a bold text inside the JTextArea in Java?
A JTextArea class can extend JTextComponent and allow a user to enter multiple lines of text inside it. A JTextArea can generate a CaretListener interface, which can listen to caret update events. We can set a font to a text inside the JTextArea by using setFont() method.
Example
import java.awt.*;
import javax.swing.*;
public class JTextAreaTextBoldTest extends JFrame {
private JTextArea textArea;
public JTextAreaTextBoldTest() {
setTitle("JTextAreaTextBold Test");
setLayout(new BorderLayout());
textArea= new JTextArea();
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
Font boldFont=new Font(textArea.getFont().getName(), Font.BOLD, textArea.getFont().getSize());
textArea.setFont(boldFont); // bold text
add(textArea);
setSize(375, 250);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String[]args) {
new JTextAreaTextBoldTest();
}
}Output
