Can you please help me the JAVA program?
Let\'s write a program that will produce a file that can be opened by Excel or LibreOffice Calc. Go to Getting Started and look up the grading weights used for this course. As an example, we\'ll use the following table, but you should use the values you find in Getting Started. Write a class SSRow. Objects of this class should keep track of String name, int score, int weight, String calc. SSRow also has a to String method that returns this data in order, separated by commas. name + \", \"+ score +\", \"+ weight +\", \"+ calc Further design of the SSRow class is left to you. Add what you need, but don\'t get carried away. Write a class SSWriter that has a main method. For each of the grading categories (Lab. Reading Quizzes. Group Work. Midterm. Project. Final. Instructor Discretion). query the user for a score, and create the following SSRow objects: \"Lab\", : 20. \"=B1Times C1/100\" \"Reading Quizzes\". , 10, \"=B2TimesC2/100\" \"Group Work\". , 10, \"=B3 Times C3/100\" \"Midterm\". . 20, \"=B4 Times C4/100\" \"Project\", . 15, \"=B5 Times C5/100\" \"Final\", . 20, \"=B6 Times C6/100\" \"Instructor Discretion\". , 5, \"=B7 Times C7/100\" Open a file for output with a file type of csv (say MyGrades.csv, for example). Write the to String value for each SSRow to the file. Finally, write a row \"average\".=(D1+D2+D3+D4+D5+D6+D7) Open MyGrades.csv with Excel or LibreOffice Calc.Solution
