A. Introduction
In Student class, we can use new Student() to create a new object, then set all attribute values. This is not the best practice to create 100 students.
There is a type of methods that are specialized in creating objects, these are constructors.
As a matter of fact, you can define multiple constructors and use them to "initialize" objects.
Hint: Do you recall Scanner in = new Scanner (System.in)?
