Bonus challenge: Convert the Help class developed in
Try This 4-1
into a Swing-
based GUI program. Display the keywords (
for
,
while
,
switch
, and so on) in a
JList
.
When the user selects one, display the keyword's syntax. To display multiple lines of
text within a label, you can use HTML. When doing so, you must begin the text with
the sequence
<html>
. When this is done, the text is automatically formatted as de-
scribed by the markup. In addition to other benefits, using HTML enables you to cre-
ate labels that span two or more lines. For example, this creates a label that displays
two lines of text, with the string "Top" over the string "Bottom".
