A student marking system receives input of student’s total mark from lecturer. If a studentgets total mark of 75 or above, the system will print ‘A’. If a student’s mark is between 65 to74, the system will print out ‘B’. While ‘C’ will be printed out if the mark is between 50 to 64.Whichever the total mark is below 50, ‘F’ will be printed

A school has following rules for grading system:           a. Below 25 - F               b. 25 to 45 - E             c. 45 to 50 - D               d. 50 to 60 - C          e. 60 to 80 - B              f. Above 80 -    A                                                                                                                     Ask user to enter marks and print the corresponding grade.

Problem StatementA computer science teacher assigned the students a programming task that calculates and displays grades based on test marks. The teacher wants the program to take a student's test mark as input and determine their grade using the following criteria:If the mark is between 90 and 100 (inclusive), assign grade A.If the mark is between 80 and 89 (inclusive), assign grade B.If the mark is between 70 and 79 (inclusive), assign grade C.If the mark is between 60 and 69 (inclusive), assign grade D.If the mark is between 45 and 59 (inclusive), assign grade E.For marks below 45 assign grade F.If the mark is greater than 100 or a negative number, it displays "Invalid input". Help the students to accomplish the given task.Note: This question helps in clearing AMCAT exam.Input format :The input consists of a single integer, representing the student's mark.Output format :The output displays "Grade: " followed by the grade for the given mark based on the given criteria.If the mark is greater than 100 or a negative number, the output displays "Invalid input".Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:0 ≤ student's mark ≤ 100Sample test cases :Input 1 :100Output 1 :Grade: AInput 2 :85Output 2 :Grade: BInput 3 :79Output 3 :Grade: CInput 4 :63Output 4 :Grade: DInput 5 :56Output 5 :Grade: EInput 6 :0Output 6 :Grade: FInput 7 :-5Output 7 :Invalid inputInput 8 :126Output 8 :Invalid input

State and explain four features of java programming language (4 Marks)d) Write a Java program that determines a student’s grade. The program will read three types ofscores(quiz, mid-term, and final scores) and determine the grade based on the following rules: -if theaverage score >=90% =>grade=A -if the average score >= 70% and <90% => grade=B -if theaverage score>=50% and <70% =>grade=C -if the average score<50% =>grade=F(7 Marks)
