ARRAYS - Java Programming: From Problem Analysis to Program Design - page 589

Note that the constructor with parameters of the class StudentData has a variable
length formal parameter. The method courseGrade also consists of a variable length
formal parameter. The following program uses the class Student to keep track of
students' names, test scores, and course grades:

public class TestProgStudentData
{

public static void main(String[] args)
{

StudentData student1 =
new StudentData("John", "Doe",
89, 78, 95, 63, 94);

StudentData student2 =
new StudentData("Lindsay", "Green",
92, 82, 90, 70, 87, 99);

System.out.println(student1);
System.out.println(student2);

}

}
Sample Run:
John Doe 89.00 78.00 95.00 63.00 94.00 B

Lindsay Green 92.00 82.00 90.00 70.00 87.00 99.00 B

We leave the details of the preceding output as an exercise.

Exercise 28 at the end of this chapter.

Two-Dimensional Arrays
In the previous section, you learned how to use one-dimensional arrays to manipulate
data. If the data is provided in a list form, you can use one-dimensional arrays. However,
sometimes data is provided in a table form.
Suppose you want to keep track of how many cars of a particular color a local dealership
has in stock. The dealership sells six types of cars in five different colors. Figure 9-15
shows a sample data table.
