bookClass Attributes

Attributes are some variables inside the class that describe each object. Let’s demonstrate it with two classes – Rectangle and Student.

We can represent Rectangle by its height and width. Add these Attributes to the class definition:


              
1234

            
class Rectangle{
  height;
  width;
}
copy

If you need to describe student in some way, you can create class Student with attributes like, for example, name and university.


              
1234

            
class Student{
  name;
  university;
}
copy

Task

Add more attributes to the class Student: age and gpa variables.
