Object-oriented programming (OOP) has emerged as a significant software development methodology. This course introduces the important concepts of object-oriented design and languages, including data abstraction and encapsulation, inheritance and dynamic method dispatch, subtyping, generics, and OOP-based concurrent programming paradigms. We will learn advanced programming techniques that use these concepts and explore how OOP language features are implemented by compilers. The course will include significant programming assignments, stressing object-oriented design. Programming assignments will use the programming language Scala, which will also be introduced in the course.

Prerequisites:Programming Languages (CSCI-GA.2110)


Throughout the semester, we will investigate the following topics in detail among others:

  • Object-oriented programming in Scala
  • Composition, inheritance, and subtyping
  • Method overloading and overriding
  • Implementing OOP features
  • Functional programming with objects
  • Generic programming with objects
  • Covariance, contravariance, and higher-kinded types
  • Concurrent programming with objects
  • Design patterns



We will use Piazza for course-related discussions and announcements. I encourage you to ask questions when you are struggling to understand a concept - you can even do so anonymously.


Homework assignments and projects (50%), final exam (50%).

Late Submission Policy

Late submissions of homework solutions and projects will be graded with a 10% penalty per day of late submission. Solutions will not be graded if they are submitted later than one week after the specified deadline.

Academic Integrity

Please review the departmental academic integrity policy. In this course, you may discuss assignments with other students, but the work you turn in must be your own. Do not copy another student's work. You must do the projects as a group but not with other groups and without consulting previous years' students, code, etc. You should help other students and groups on specific technical issues but you must acknowledge such interactions. Copying code or other work without giving appropriate acknowledgment is a serious offense with consequences ranging from no credit to potential expulsion.
