Writing Your First Java Program
Welcome to the start of your journey with Java! In this track, we’ll learn what Java is and write our first program!
Learn how to write object-oriented programs by building your own classes. Then take a look at some of the most common built-in Java classes.
Conditionals and Control Flow
Learn how to use conditionals - one of the most important tools in programming.
A Deeper Dive Into Classes
Take a deeper look at how classes work in Java. Explore String methods as well as some of the more advanced features of your own classes.
Arrays and Loops
Create Arrays and ArrayLists, loop through those data structures, and ultimately create two-dimensional versions of these objects.
It’s time to put your Java knowledge to the test! Try solving some of our code challenges involving arrays, loops, Strings, and more!
What is an algorithm? How do we know if an algorithm is efficient? Let’s dive into some of these Computer Science concepts.
Hands-on learningDon't just watch or read about someone else coding — write your own code live in our online, interactive platform. You'll even get AI-driven recommendations on what you need to review to help keep you on track.
Projects in this skill path
Planting a TreeWrite your first Java program from scratch by introducing yourself to users and planting a tree for them. You'll practice creating a class, defining the main method, and organizing print statements.
Java Variables: Mad LibsIn this project, we're going to practice creating variables and printing. We're going to put your skills to the test by generating a story, Mad Libs style.
Math MagicIt's time to build fluency with operators in Java. In this project, we're going to practice arithmetic in Java so you can hone your skills and feel confident taking them to the real world. Why? Practicing computing integer values with Java's arithmetic operators will help you with a wide, wide range of Java tasks in the future. What's next? Some math, more Java, and a sprinkle of magic. You got this!
