Write a program, BytePe1.java, that reads a binary file ClassList.dat, calculating the grades and prints the results. The file layout is as follows: Binary data file contains: Data type Data item UTF Student Name Student number integer double Grade in class 1 double Grade in class 2 double Grade in class 3 double Grade in class 4 Requirements: Read the binary data file not knowing how many records are in the file. Compute the average of grades, and print the average as the last column of the data read. There are three examples shown. However, the data file contains more data than shown. Do not program for only three people. The program must handle all the data, and terminate without errors. Use the printf method for formatting. Make sure your headings, and column output matches exactly. Blank spacing between columns does not have to match exactly. Partial sample of the output: ID Gradel Grade2 Grade3 Grade4 Avg. 93.3 Name Kathryn Morris 193038393 93.2 94.3 89.0 96.5 John Finn 394720953 89.5 92.7 77.8 96.5 89.1 Jeremy Ratchford 252648093 75.6 88.5 67.0 98.3 82.4
