edX: Introduction to Java Programming: Writing Good Code

 with  Carlos Delgado Kloos, Carlos Alario-Hoyos , Iria Estévez-Ayres , Jorge Blasco and Julio Villena Román

This is an introductory course to learn programming with Java designed to teach how to code good programs in Java, understanding “good” as both correct and efficient. Basic principles of software engineering will be introduced to make it easier for our future self and others to reuse code. Ethical issues and the intellectual property of our programs will also be addressed in the last part of this course. Examples and case studies will be provided, so that learners can implement simple but increasingly complex programs in Java.

Emphasis is put on immediate feedback and on having a fun experience. Programming knowledge is not only useful to be able to program today’s devices such as computers and smartphones. It also opens the door to computational thinking, i.e. the application of computing techniques to every-day processes.

This course is designed taking into account the subset and recommendations of the College Board in order to prepare learners for the Advanced Placement (AP) Computer Science A exam..


1. Debugging
The first week starts from basic errors that occur at compile time and at run time when developing programs, and introduces debugging as a powerful and flexible strategy to detect and correct errors. The Eclipse IDE Debugger will be used to illustrate the debugging process with practical examples.

2. Reasoning & Testing
The second week addresses formal mechanisms to test that programs do what is expected of them, introducing unit testing processes, particularized in the JUnit framework for testing programs written in the Java language.

3. Complexity
The third week analyzes programs from the point of view of efficiency in the use of resources, such as computation time and storage, and presents simple mechanisms to improve the efficiency of Java programs.

4. Software Engineering
The fourth week introduces basic principles of software engineering with the aim to improve robustness, modularity, reusability and maintainability of programs.

5. Ethics
The last week studies ethical issues related to software development, including privacy, legal issues, intellectual property rights, and social ramifications.

What are MOOCs?
MOOCs stand for Massive Open Online Courses. These are free online courses from universities around the world (eg. Stanford Harvard MIT) offered to anyone with an internet connection.
How do I register?
To register for a course, click on "Go to Class" button on the course page. This will take you to the providers website where you can register for the course.
How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you.  They also have student discussion forums, homework/assignments, and online quizzes or exams.
