I've inspected the Java class documentation for Color and found that I can generate a Color object from a hex code string (e.g. "#FFFFFF") using the Color.decode(); method.
I would like to implement the reverse process for a project I am working on, but there doesn't seem to be a method already built in to the class for this.
Is there an easy way to do this?
String.format("#%06x", color.getRGB() & 0x00FFFFFF)
The masking is used for removing the alpha component, in bits 24-31
Color color = Color.BLUE;
Formatter f = new Formatter(new StringBuffer("#"));
f.format("%02X", color.getRed());
f.format("%02X", color.getGreen());
f.format("%02X", color.getBlue());
f.toString(); //#0000FF

The answer has a method to convert a color to it's hex value.
There is another way. Thought I just add this alternative.
// ARGB = (255, 255, 0, 0) (Red)
// hex -> "ffff0000"
String hex = Integer.toHexString(color.getRGB());
// Reduced to RGB: hex -> "#ff0000"
hex = "#" + hex.substring(2, hex.length());
