Color setting
Is there a way to use 1 value to set the color of a Color object in Java? I want to pass 1 value in to set the Color. What's the easiest way to do this? Thanks.
Yes, the Color class does have a constructor with one parameter. (public Color(int rgb).) So if your goal is to pass in one object, that would be the easiest way to do it.

Easiest at least for the code you would have to write, anyway. It delegates the complexities of building that one object to somewhere else; I don't know if that's a concern for you.
Thanks Paul. You happen to have a good link how how to convert a value to the object expected? I'm guessing it isn't as easy as passing in a hexadecimal value? :-)

Color class constructor.

It is in fact as easy as passing a hex number.

Color red = new Color(0x00ff0000);
Cool thanks.
The hexadecimal way is great but here's what I'm trying to do. I need to load a value from a textfile and use that value to set the color of objects on an applet. What's the best/easiest format to store within a text file and convert it (if need be) to something that can be used to set a color? Appreciate any help on this. Thanks again.
The nextInt() method of Scanner is probably the easiest way to extract an int from a text file.
You could also use three ints in the range 0...255 (0...0xff) inclusive, or four floats in the range 0f...1.0f inclusive, and the three-arguments or four-arguments constructor of Color.
