Java is one of the most popular programming languages. Java offers both object-oriented and functional programming features.
We take a hands-on approach using a combination of JShell and Eclipse as an IDE to illustrate more than 200 Java Coding Exercises, Puzzles, and Code Examples. This course assumes no previous ( beginner ) programming or Java experience. If you’ve never programmed a computer before, or if you already have experience with another programming language and want to quickly learn Java, this is a perfect course for you.
