Pro 5.rar - FILES NEEDED HEREWrite a program in Java and run it in BlueJ according to the following specifications:The program reads a text file with student records (first name, last name and grade) and prints them in the terminal window.After the name and grade it also prints the type of the grade: excellent (> 89), ok [60,89], and failure (< 60).Then the program prints the number of students, and their average grade and also the number of students and their average in each grade category (excellent, ok, and failure).For example, with the input file students.txt the program must print the following:John Smith  90 excellentBarack Obama  95 excellentAl Clark  80 okSue Taylor  55 failureAnn Miller  75 okGeorge Bush  58 failureJohn Miller  65 okThere are 7 students with average grade 74.0There are 2 excellent students with average grade 92.5There are 3 ok students with average grade 73.3333There are 2 failre students with average grade 56.5Requirements and restrictionsUse the Student.java and Students.java classes from the course website to represent and process student records and modify them accordingly:The encapsulation principle must be strictly enforced.The main method in class Students should only read the text file, and print student records (student names, grade and grade type) and statistics (number of students and averages).No other kinds of computations should be included in the main method (e.g. checking student grade intervals and student type, counting students, totaling grades).All counting, totaling, computing averagas, checking grade intervals, and assigning grade types to students should be implemented in class Student. Hints: use static variables in class Student and add methods to compute and return (or print) averages. Modify the toString() method to return the grade type too.When you write your programuse proper names for the variables suggesting their purpose.format your code accordingly using indentation and spacing.use multiple line comment in the beginning of the code and write your name, e-mail address, class, and section.for each line of code add a short comment to explain its meaning.
