Learn to write cleaner, more modular, and more scaleable code in Python by gaining a master of Object Oriented Programming (OOP). 

You'll start with the basics of object oriented programming and build up to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way you'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

// Student Class
class Student {

  // Private Fields
  private String name;
  private String rollNumber;


  // getter function for name
  public String getName() {
    return "";  
  }

  // setter function for name
  public void setName(String x) {
    this.name = x;
  }

  // getter function for roll number
  public String getRollNumber() {
    return this.rollNumber;  
  }

  // setter function for roll number
  public void setRollNumber(String x) {
    this.rollNumber = x;
  }

}

## Explanation

* We have implemented the `Student` class, which has two private properties -- `__name` and `__rollNumber` -- that are initialized in the set methods.

* In **line 6**, we implemented `setName(name)`, a *method* that sets the `__name` *property*.

* In **line 9**, we implemented `getName()`, a *method* that returns the `__name` *property*.

* In **line 12**, we implemented `setRollNumber(RollNumber)`, a *method* that sets the `__rollNumber` *property*.

* In **line 15**, we implemented `getRollNumber()`, a *method* that returns the `__rollNumber` *property*.
