write code for this project that fullfills all the requirments. Need in done asap before 4 pm est. Thank you so much!

Introduction In this project, you will apply the knowledge of decision statements (e.g. branching statements), variables, assignments, string operations, inputs and outputs, basic algorithm design, compiling. program testing and debugging. You will create a working pragram that can calculate grades based on the set standard. IPlease note that this arade calculator is NOT used to calculate the grade for this course!/ Assignment Write a single-fle Java program called GradeCalculator (file name: GradeCalculator.java). This program should be able to calculate a student's current grade, to find the average score that student needs to obtain for the rernaining items in arder to achieve a certain desired letter grade. We will use the following grading scale to compute the final letter grade. Note that we only deal with the letter grade, no +or - fallowing the letter. Note: [ and ] : inclusive; ( and ): exclusive. The final course grade includes labs, quizzes, projects, participation, exam 1, exam 2, and final exam. Follow the instructions below for writing the program. 1. The program should first ask the user to input a letter grade thry want to receive. Note that the user input of the letter grade may be valid or invalid. 2. Then, the program asks the user if they know the scores for each graded item. 3.1 If the user does know [2.), i.e. the scores far each graded item, by entering " y " or "pes" luppercase or lowercase letters or a mix), the propram will ask the user the scores for each graded item. Each item is graded with a number in a 100-point grading scale. 3.2 If the user daes nat know one or mare scares for each graded itern, the user will enter " n " or anything else. Any input other than " y " or "yes" (by ianoring case) means NO - i.e, the user finalOverallscore: minimum score in the range of the letter arade the user wants to obtain. does not know the score. weight tg : the weight of the graded item gf. scoreac the score achieved in the grading item gi. 4. Exam 1, exam 2, and final exam are taken in order. Therefore, if the user does not know the totwKnownGrodeWelght: sum of we ghts of grading items with known scores. score for exam 2, the program will not ask the user to enter final exam score. If the user does (Hint: if value of totaknownGradeWeight is 100, ther all grades are known. No calculation will not know the score for exam 1 , the program will not ask the user to enter exam 2 score or final be needed.) exam score. 7. As you see, the desired letter grade is achievable only if the average score for the remaining 5. Once the user has entered the desired final letter grade, the weights of all graded items, and graded items is no greater than 100 . For instance, it is easy to understand that the user cannot the user's known scores, the program will calculate and display the current grade based on the expect an A grade if he/she has alreardy scored too low for all existing graded items. By noting follawing farmula: that fact, do the following: 7,1 If the user's desired letter grade is achievable, the program will print the average score for the user to obtain that final letter grade. weight ti : the weight of graded item gi 7.2 Otherwise \{when the user's desired is not achievable\}, the program will print that the user scorsa the score abtained in the graded item gi cannot achieve that letter grade. totaKnownGradeWelght: sum of we ahts of the araded items of known scores In our example, let's assume that the user's desired letter arade is A According to the formula, The Sigma symbol is the sum of each weighted score. the user needs to score a grade average greater than or equal to 91.07692 for the labs, quizzes, projects, participation, and final exam to obtain the A grade for the course. Fxample: the user wanis to get A; the user only know's examn 1 (-92), exarn 2 (-8,5). Fxamn 1 carries 15% weight and exan 2 carries 20% weight. The current scofe is expressed as follows: The program must display the gride average or anv ivernges with two decimil places as shown in the examples. (Hint: how to display a number with two decimal places? Recall a previous lab assignment.)
