JTextField not displaying super/subscript

Question

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

public class practice9 {

public static void main(String[] args) {
    JButton b = new JButton();
    b.setBounds(10, 10, 150, 150);
    JLabel l = new JLabel("ell");
    l.setText("<html>+ax<sup>2</sup>+bx<sub>2</sub>+c</html>");
    b.add(l);
    JTextField t = new JTextField();
    t.setBounds(10, 300, 150, 150);
    t.add(l);

    JFrame f = new JFrame("");

    f.setVisible(true);
    f.setLayout(null);

    f.setBounds(10, 10, 500, 500);
    f.add(b);
    f.add(t);
}
}

I was working on a calculator and wanted to display superscripts. I was successful in doing so on a label using the HTML, but failed to repeat it on a text field.

Is it impossible to do it in a text field (i.e. display sub/superscript) or is there a way?

please don't use `null` layout. call `f.setVisible(true)` in the end after adding all the component. — Braj, Jun 22 '14 at 08:44
I'm pretty sure that `JTextField` doesn't support this because it's using a `PlainDocument` — MadProgrammer, Jun 22 '14 at 08:46
@user2837260 The suggestion not to use a `null` layout may not answer this question, but it's likely to answer a lot more in the future ;) — MadProgrammer, Jun 22 '14 at 08:47
so my only option is to replace the textfield of my calculator with a JLabel? — user2837260, Jun 22 '14 at 08:47
but i like working with 'null' layout..it gives me the freedom to place stuff on the frame wherever i want!! — user2837260, Jun 22 '14 at 08:49
absolute positioning might work on your system but think about other system that have different resolution and OS. What about if I re-size the frame? — Braj, Jun 22 '14 at 08:50
Please have a look at [Editor Panes and Text Panes](http://docs.oracle.com/javase/tutorial/uiswing/components/editorpane.html) that supports HTML formatting. — Braj, Jun 22 '14 at 08:53
And different fonts and rendering pipelines, all these things change the amount of space components need. Pixel perfect layouts are an illusion on modern GUI design — MadProgrammer, Jun 22 '14 at 08:53
@Braj The trick would be keeping to a single row height and allowing it to overflow... — MadProgrammer, Jun 22 '14 at 08:54
`HTMLDocumentEditor` is a complete example, cited [here](http://stackoverflow.com/a/10167091/230513). — trashgod, Jun 22 '14 at 09:12
As an aside, the logic used in that code is hard to understand. For example. 1) Why try to add a `JLabel` to a `JButton` when we can simply call `b.setText("..")`? A button is one of the components that *does* support (simple) HTML. 2) Why have such a 'tall' `JTextField` that can only accept a single line of text, then give it a small (standard) font? — Andrew Thompson, Jun 22 '14 at 09:41
this was just a dummy code..to sort things out for the main project.. — user2837260, Jun 22 '14 at 09:59
Well now is the time to sort out crap code & get the design right, no? — Andrew Thompson, Jun 22 '14 at 12:19
As an aside, a tip. Add @MadProgrammer (or whoever - the `@` is important) to *notify* a person of a new comment. — Andrew Thompson, Jun 22 '14 at 12:20
