Hi All,
I need to write a correct "if" statement in a test program
that is looking at vectors of pixel colors.
This program below, at line 64, shows System.out.println(clr); and
the output is written is: "java.awt.Color[r=0,g=0,b=0] "

My attempt at writing "if" statements are line 65 and 66
if (clr == 0,0,0) System.out.println ("Here is color black");
if (clr == java.awt.Color[r=0,g=0,b=0]) System.out.println ("Here is
color black");

If the width of any line is greater than the maximum number
The error list is note below:
9 errors found:

Your help is appreciated, thanks
