About my class and why it's not detecting java.awt.Color?

Question

I've got a issue with the program I'm writing - this is an APCS A class so there is an APCS.lib - it includes the DrawingTool Class that is used in the program. I'm having issues with the import java.awt.Color statement:

There is a driver that is executed for the entire program but my question is in the line import java.awt.Color; and line 33 - pencil.SetColor(Color, red); . Not sure my drjava is not detecting that java.awt.color import and still giving me a "cannot find symbol/variable error." The program draws a house.

Answer 1

java.awt.Color has a constant red . It should be

pencil.setColor(Color.red);

in line 33. Have a look at its the javadoc for Color .

Answer 2

You have a syntax error where you have pencil.setColor(Color, red);

This line should be: pencil.setColor(Color.RED);

By the way welcome to SO!

Answer 3

To elaborate on the given answers:

The setColor method requires a single Color object as its parameter. You cannot pass it Color , as that is a class, and you cannot pass it red , as that doesn't mean anything to the compiler (it tries to find a variable named red ).

The trick is to access the static variable Color.red or Color.RED (which is a Color object), and pass it into the method, as the other answers have done. As mentioned in another answer, the javadocs for Color may help you here.
