In this free online course, you’ll learn the key concepts of object-oriented programming (OOP) as well as fundamental programming techniques. You’ll apply your newly acquired knowledge by implementing hands-on programming exercises in the Java programming language. The course will be completed by an exercise to model a small, object-oriented, real-world scenario. After completing this course, you’ll be able to model and implement small programs in Java and apply OOP best practices.

Course Summary
In this course, you’ll learn the key concepts of object-oriented programming (OOP) as well as fundamental programming techniques. A key concept of OOP is to distribute tasks between several suitable components. Each of these components has its own state and behavior and can communicate with other components. You’ll apply your newly acquired knowledge by implementing hands-on programming exercises in the Java programming language. The course will be completed by an exercise in which you’ll model a small, object-oriented, real-world scenario.
For a better understanding, the programming exercises are combined with a detective story. Help Duke to solve his mysterious new case!
After completing this course, you’ll be able to model and implement small programs in Java and apply OOP best practices.

Christiane Hagedorn did both her bachelor's and master's degree in Media Informatics at the Beuth University of Applied Sciences in Berlin. Now she is a PhD candidate at the Hasso Plattner Institute and explores the potential of game-based learning in e-learning contexts.
In her leisure time, Christiane is singing in a choir, likes to travel the world, and taking pictures while doing some hikes. She also loves playing digital and non-digital games, which is one of the reasons for choosing her research topic. In the past, she worked on several game projects. In addition, she has developed a great passion for teaching.
Ann Katrin Kuessner graduated with a Bachelor of IT-Systems Engineering at the Hasso Plattner Institute and is currently pursuing her masters. She currently works as a software engineer for openWHO.org, the sister platform of openHPI and openSAP. In her free-time, you can mostly find her outside doing sports, preferably in the mountains. Additionally, she works voluntarily as a ski instructor for her skiing club and gives workshops and supervises camps for STEM topics.
