When you tell an acquaintance your telephone number, you do not recite the digits one by one at a constant rate, as in "3, 3, 7, 2, 3, 4, 8, 3, 9, 2." Rather, you might say, "3, 3, 7 . . . 2, 3, 4 . . . 83, 92." This exemplifies , a strategy to enhance memory.

Acolor class has three public, integer-returning accessor methods: getred, getgreen, and getblue, and three protected, void-returning mutator methods: setred, setgreen, setblue, each of which accepts an integer parameter and assigns it to the corresponding color component. 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. alphachannelcolor also has a method named dissolve (void-returning, and no parameters), that causes the color to fade a bit. it does this by incrementing (by 1) all three color components (using the above accessor and mutator methods) as well as the alpha component value. write the dissolve method.
