Public static String getVerticalBars(int maxRows, int maxCols, int bars, char color1, char color2, char color3) - This method returns a string with a number of vertical bars that correspond to the bars parameter. To compute the size of each vertical bar, divide maxCols by the specified number of bars. The first vertical bar will use color1, the second color2, and the third color3. If more than 3 bars are present, we will start again with color1. If the computed size for a vertical bar is less than 1, or any of the colors is invalid, the method will return null and no diagram will be generated. The method MUST not rely on System. out. println(). For example, calling DrawingApp. getVerticalBars(10, 12, 3, 'R', 'G', 'B'); will generate the string:

Write a grading program for a class with the following grading policies: a. there are two quizzes, each graded on the basis of 10 points. b. there is one midterm exam and one final exam, each graded on the basis of 100 points. c. the final exam counts for 50% of the grade, the midterm counts for 25%, and the two quizzes together count for a total of 25%. (do not forget to normalize the quiz scores. they should be converted to a percentage before they are averaged in.) any grade of 90 or more is an a, any grade of 80 or more (but less than 90) is a b, any grade of 70 or more (but less than 80) is a c, any grade of 60 or more (but less than 70) is a d, and any grade below 60 is an f. the program will read in the student’s scores and output the student’s record, which consists of two quiz and two exam scores as well as the student’s average numeric score for the entire course and final letter grade. define and use a structure for the student reco
