Height of JLabel to grow with number of lines

Question

I want my JLabel to be the height required for the particular string that is assigned to the text. The text string can can have any number of lines, which use the \n in the string. So if you have a string the "Hello\nit\nis\nme\n" the height of the label will automatically be adjusted to fit the 4 lines.

How to achieve that?

You might want to say it a 3rd time. :) Myself I'd use a JTextArea configured to look like a JLabel. — Hovercraft Full Of Eels, May 30 '12 at 13:56

Use proper JTextComponent rather than use HTML formatted text in the JLabel
I think that for "Hello\nit\nis\nme\n" should be disabled JTextArea right JComponent

A JLabel¹ would typically ignore the new-line character. To get multi-line text, either use a mutli-line component such as a JTextArea² or use HTML formatting in the label.

Here is an example of using HTML formatting (screenshot above). The example uses styles (CSS) to cause the line breaks to be inserted automatically. This is much easier than calculating where to insert line-breaks in text blocks manually.
Of course, a JTextArea having methods like setLineWrap(true) & setWrapStyleWord(true) also handles line wrap automatically.
