String length in pixels in Java

that does not use any GUI components?
It depends on what you mean here. I'm assuming you mean you want to do it without receiving a `HeadlessException`.
The best way is with a `BufferedImage`. AFAIK, this won't throw a `HeadlessException`:
Font font = ... ;
BufferedImage img = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
FontMetrics fm = img.getGraphics().getFontMetrics(font);
int width = fm.stringWidth("Your string");
Other than using something like this, I don't think you can. You need a graphics context in order to create a `FontMetrics` and give you font size information.
Problem
Is there a way to calculate the length of a string in pixels, given a certain `java.awt.Font` object, that does not use any GUI components?
