you will draw grades of students as a horizontal bar chart, as shown in Figure 1 and 2. Your program will load input data from a text file. Input data contains student names and exam grades for students. Sample input data files (student_info1.txt and student_info2.txt) are shown in Box 1 and Box 2. Input data files start with an integer value denoting the number of exams. For instance, for the first data file -student_info1.txt-, there are five exam grades. In the second file, there are three exams. Total grade of each student can be maximum 100. Your program will read a single file at each run, and plot grades for all students found in the input data file. Design your algorithm in such a way that if you change the input file, it should adjust the parameters of the bar charts so that all student data fits into a figure window. For instance, you need to compute the height of rectangles according to the number of students in the input files. As can be seen from Figures 1 and 2, rectangle heights are bigger for nine students found in the second data file. In these examples, figure dimensions are W:1500xH:800. You may adjust figure dimensions according to your screen resolution. You should store students in a Student array. The UML class diagram of Student class is shown in Figure 3. Name data field is private. Student grades are stored in the public grades array. You should automatically create grades array according to the number of exams, provided in the input data files. Note that in each data file, exam numbers are different. Tip: Create grades array in the second constructor.

Please help me about this assignment. if you attach mentioned java classes it will mean so much to me. Thanks

I NEED MAIN CLASS ABOUT THIS ASSIGNMENT ( WHICH INCLUDES READING FILE FROM A TXT FILE CODE, PLACING IT TO A ARRAY and others.. ) TXT FILES ATTACHED AS A IMAGE IN !!!FIGURE 3!!!

IMPORTANT NOTE : Its second time asking this question. The other answer was so weak and it was only including a particilar part of the student class (not the main class).

Code will and should look like Fig 2 or Fig 1. you can decide which one you want to do.
