The programming foundations course is part of the five-course Java Programming and Software Engineering Fundamentals Specialization. You can enroll in a single course to get started and earn a certificate, or audit the online coding class and review the materials for free. The Java Programming and Software Engineering Fundamentals Specialization is considered a beginner specialization, and if you subscribe to one course, you'll be included in the whole specialization.
The course requires a laptop or desktop computer for Java programming and that you make a free account on CodePen.io. If you choose to continue with the other courses, you'll need to install Bluej, free software for Java development.
This course would be most useful if you're interested in coding for websites.
What it costs: Coursera operates more like a traditional online college course with enrollment windows. Sometimes the certificates you earn can apply as a credit at an institution, but it has to be stated. When you sign up for Coursera, you get a seven-day free trial, and then it starts at $49 a month. You can also choose to audit the class for free, which lets you read and view the course content only.
