I am hoping to be able to build a variable as a string but then have it actually be used as the correct type.

Example: I want to use graphics.setColor(color.red)

Is there a way to build the variable? String myColor = "Color." + Pull value at runtime myColor would then have a value of "Color.red"

So in my head the code would look like this

String myColor= "Color." + (color selection)

graphics.setColor(myColor.value());

So Ideally it would always set the color to whatever the current color selection is from a Gui

Can you do this?

Thanks

Just use an instance of `Color` and change it as needed – MadProgrammer Jul 19 '17 at 23:44
If you are unfamiliar with it, try looking into java reflection API. – Maglethong Spirr Jul 19 '17 at 23:47
https://docs.oracle.com/javase/tutorial/reflect/ if you _really_ want to do this, but you should really just map strings to colors. – Jeffrey Bosboom Jul 19 '17 at 23:48
