Question

Can you compare two colors in java ? Such as comparing to see if a color X is black or not. Something like:

        Color X = new Color(R,G,B);
         if ( X == Color.BLACK) { 
              System.out.println("True");
         }

Answer 1

Colors are objects, like Strings, so you should compare them using:

myColor.equals(Color.BLACK)

instead of

myColor == Color.BLACK

The second compares whether the two variables point to the exact same object in memory, whereas the first compares whether they are two different color objects that both the same shade of color (black).

In general, use == for primitive types (like int), and .equals(...) to compare object types.
