C:\Sun\AppServer\jdk\bin\Student.java:31: array dimension missing
Student pupil[i] = new Student[];
^
1 error

I have tried corrected but it seems that I am not setting up my array correctly.

Based on your comment,

// create an array of 10 student objects from class Student...

your array declaration would look like

Student[] students = new Student[10];

Note that you want this outside your for loop, not inside; you want to create the array, then visit each element, right?

Now, this just gives you an array of 10 Student variables; the variables are all null. If you need objects, then you need to create those too; for example, inside your for loop, at the top, you might have

students[i] = new Student();

this would fill each element of the array with a Student object as you visited it.
