Java Programming for Complete Beginners

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 demonstrate over 200 java coding exercises, puzzles, and code examples. This course does not assume any prior programming (beginner) or java experience. If you’ve never programmed a computer before, or if you already have some experience with another programming language and want to learn java quickly, this course is perfect for you.

In over 250 steps, we explore the most important features of the java programming language, including:

Fundamentals of java programming – expressions, variables, and print output

Java operators – java assignment operator, relational and logical operators, short-circuit operators

Java conditions and if statement

Methods – parameters, arguments, and return values

Object oriented programming – class, object, state and behavior
