Is there a way to make a java.awt.Font strike through?

Basically, create a new AttributedString out of your string, add a STRIKETHROUGH attribute, and draw.
NOTE: This will NOT make the FONT strikethrough, but you can set the text to that font and then strikethrough on the text. This is simply another way of doing it. Rich's answer actually makes the font strikethrough.
