Activities

To give yourself an array of experiences to draw from later, you can expand your knowledge of this hour's topics with the following activities:

• Create a program that uses a multidimensional array to store student grades. The first dimension should be a number for each student, and the second dimension should be for each student's grades. Display the average of all the grades earned by each student and an overall average for every student.
• Write a program that stores the first 400 numbers that are multiples of 13 in an array.

To see Java programs that implement these activities, visit the book's Web site at http://www.java24hours.com.
