Java Programming
This course is a support in French for the programming lecture (in Java) in the first year of the ISC programme at HEIA-FR. This course offers exercises that will be done in part during class time. Be aware that the exercises do not replace the series. The exercises present theoretical concepts using examples, propose programming problems to be solved and answers to be given to questions (in the form of multiple choices). The prerequisites for this course are basic programming and mathematical skills. Object oriented programming is not a prerequisite.

APCS Keate
This is an introductory Java course complement to the AP Computer Science A course taught using AP CSAwesome by Barbara Ericson and Beryl Hoffman's on Runestone Academy. The College Board AP Computer Science A course webpage and information, including the course overview, can be found here. The activities presented are based on the official Java Documentation. The target audience for this course are high school students with little or no experience programming in Java using the free companion textbook, AP CSAwesome. This course covers the basics of object-oriented programming through Java from creating primitive data type variables and performing operations on them, control structures, different types of iteration, and simple data structures: arrays, ArrayLists, and 2D arrays. This course also includes using Java's built in classes, like the String class, to create and use objects and their methods. It explores developing classes to create custom object types. The topic of inheritance is introduced as well. There are no official prerequisites for this course, but a strong background in logic or advanced algebra is recommended.

Interactive Java workbook 1
This is a demo version of volume 1 of the Interactive Java workbook multi-volume collection of tasks that covers object-oriented programming in the Java programming language. The full version of the Interactive Java workbook can be purchased here: My Ko-fi page "Programming is learned through programming." The idea is to practice programming in Java through hands-on work on a large number of diverse tasks from this collection. - It is intended for beginner programmers, but also for those who want to learn object-oriented programming in the Java programming language. - It is designed as supplementary material for existing programming courses, but still contains detailed lessons with code examples at the beginning of each chapter. - The collection contains several hundred tasks divided into several volumes. Each task has a predefined solution, a suite of tests to check the correctness of the user's solution, hints to help the user solve the task, as well as a side-by-side comparison of the user's vs predefined solution. - There are various types of tasks: questions and answers, code completion, syntax correction, code correction, program creation, alternative solution etc. - The tasks are also organized by difficulty: from easy to intermediate and difficult.
