How to get multi-line JLabel (or JTextArea that looks exactly the same) without HTML

I cannot argue that the fastest solution for multi-line JLabel is as follows (the text comes from var, and therefore I don’t want to manually put the HTML code in each x characters, so ugly):

public class JMultilineLabel extends JTextArea{
    private static final long serialVersionUID = 1L;
    public JMultilineLabel(String text){
        super(text);
        setEditable(false);  
        setCursor(null);  
        setOpaque(false);  
        setFocusable(false);  
        setFont(UIManager.getFont("Label.font"));      
        setWrapStyleWord(true);  
        setLineWrap(true);
    }
}

... sure this is not the best way to handle this ????

If you want to use the multilne label, you simply use it HTMLin your text as they support its use. Therefore, use a line brake tag </br>to break lines or place individual lines in paragraph tags <p></p>.

, HTML JLabel, <html>.

BTW , JLabel , , .:)

EDIT:

, , , . :

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.*;

public class LabelHTMLAutoResize {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame f = new JFrame();
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                JPanel p = new JPanel(new BorderLayout());
                JLabel l = new JLabel("<html><p> Some verrrry long text  Some verrrry long  Some verrrry long text dsa ads oiosi o</p>");
                l.setVerticalAlignment(SwingConstants.TOP);
                l.setOpaque(true);
                l.setBackground(Color.green);
                p.add(l);
                f.setContentPane(p);
                /* good practice is to use f.pack(); and let the size be automatically calculated but we want to show line wrapping thus frame size is set */
                f.setSize(200, 200);
                f.setVisible(true);
            }
        });
    }
}

    }
}
