Question

The bottom portrays a homework assignment for my CSCE155A class intro to computer science with java. I am supposed to write a code that creates a random generation of students and grades for them. All of the details are at the bottom, however I am very confused as to how to even start this. Please help!

Write a program that processes the statistics for grades for a group of students in the CSCE155A class. In order to do this, you need to store this information in a Java two-dimensional array of values representing points earned in the class. Dimension 1 represents the students and dimension 2 represents the categories of points, which is as follows:
