Im Stuck On this program,could someone please help me on this program? this is it here, thank you so much!
Rewrite a solution to Assignment #1 using classes. You may use your solution to Assignment #1 as a starting point, or you may use the posted solution. Your class should be called FinalMarkCalculator. It should contain fields for hybridActivities, labs, assignments, testsQuizzes, labTest, and finalExam as well as any calculated fields that you need such as finalMark. Carefully consider if any intermediate calculations (if required) should be a class field or a local variable. Note – you may use different names than are suggested here, however they should be descriptive to what is being stored in the variable (do not use num1, num2, etc.). In addition, you should have the following methods: a) default constructor – initializes to "no data" ie zeros. b) getGradesFromUser – prompts user for the individual grades hybridActivities, labs, assignments, testsQuizzes, labTest, and finalExam and reads in their input. c) calcFinalGrade – calculates the final grade d) display - displays the calculated values Rewrite your main method to declare an object reference of this class, and then call the methods on the object (method main should be in its own class).
This is my assignment 1 program just for your information to help me write the second - this are what the parts are worth hybridActivities =5% , labs =10% , Assignments =20% , MainTest = 25, TestQuizzes 10%= , finalExam = 30%
