Final answer:
A Java class will be developed to read the 'grade.txt' file, create a Student class with name and score fields, store unique student names in a HashSet, find the student with the highest grade, and count word repetitions.
Step-by-step explanation:
Java Class for Managing Student GradesTo address the tasks outlined, a Java class will be created to perform several operations. First, the program will read a file named grade.txt which contains student names and their grades. A Student class will be defined with two fields: name and score. An ArrayList will be used to store the students' data. The program will iterate through the ArrayList to find and print the student with the maximum grade. Additionally, the student names will be stored in a HashSet to ensure uniqueness. Finally, the program will count the number of repetitions of every unique word present in the file.
The Java class will encompass methods to handle file reading, object creation for every student, adding those objects to the ArrayList and HashSet, finding the highest grade, and word frequency analysis within the file.To solve this problem, you can follow these steps:Create a FileReader object to read the file grade.txt.Create a Student class with two fields: name and score.Create an ArrayList to store the Student objects.each line from the file and split it into name and score using the appropriate delimiter.Create a Student object for each line and add it to the ArrayList.Iterate over the ArrayList to find the student with the maximum grade, based on the score field.Create a HashSet and add the unique student names to it.Create a HashMap to store the count of repetitions of each unique word.Split each line into words, iterate over them, and update the count in the HashMap.
