This class performs drawings differently on different platforms. Eg:-drawing a shape in a MS Windows OS, will have different capabilities when compared with doing the same thing in a UNIX system. The drawing capabilities in each platform were achieved by implementing Platform dependent sub classes of the Graphics class. Therefore all these platform dependent classes are hidden by this Graphics class, which helps the programmer to write platform-independent code. color class and font class. Color classes  and font classes are two subclasses of the Graphics class.These two classes are used to make the text look and feel. color class The color class is used to manipulate colors using the methods and constants defined in it. Every color is a combination of red, green, blue. Combination of these three colors, which take values from 0 to 255 ...
