Java Problem The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%, C; 60%-69.99%, D; and 0%-59.99%, F. The input data file - answersheet.txt will be attached.
