Acolor class has a method getcolorname that returns a string corresponding to the common name for the color, e. g., yellow, blue, white, etc. if there is no common name associated with the color, null is returned. the class , alphachannelcolor– a subclass of color– has an integer instance variable , alpha, containing the alpha channel value , representing the degree of transparency of the color. write the method getcolorname of alphachannelcolor, that overrides the method in the color class . alphachannelcolor’s getcolorname should return the name of the color (obtained from the getcolorname method of color) prefixed with the word ‘opaque’ if the alpha value is less than 100, ‘semi-transparent’ if the alpha value is otherwise less than 200, and ‘transparent’ otherwise (separate the prefix from the color name by a blank). if the color has no name , the method should return "opaque color", "semi-transparent color", or "transparent color", according the the same alpha values as above. i have the code for the alphachannelcolor class: public class alphachannelcolor extends color{ @override public string getcolorname() { string name = super. getcolorname(); if (name == null) name = "color"; if (alpha < 100) return "opaque " + name; else if (alpha < 200) return "semi - transparent " + name; return "transparent " + name; }}what would the code look like for the color class?
