Write a program that replaces words in a sentence. the input begins with an integer indicating the number of word replacement pairs (original and replacement) that follow. the next line of input begins with an integer indicating the number of words in the sentence that follows. any word on the original list is replaced. assume that the list will always contain less than 20 word replacement pairs.

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.
