A Class assessment is based on Three Examinations, Homework and a Final Project. The weight for each category is as follows: Exam 1, Exam 2 and Exam 3 Weight 45% of the overall grade, Homework Weight 25% and Final Project Weight 30%. Write a Java Application that prompt the user to enter the three examinations (exam1, exam 2, and exam 3), homework and final project grades then calculate and display the overall grade along with a message as follow: The message is "Excellent" if the overall grade is more than 90, "Good" if the overall grade is between 80 and 90, "Average" is the overall grade is between 70 and 80, and "Poor" if the overall grade is less than 70.

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.
