Beginner to advanced Java roadmap

Software development is one of the most rewarding careers in the world of IT.

Java is one of the most in-demand programming languages around.

If the Java platform calls to you, and you want to immerse yourself in the world of Spring, Jakarta EE, Maven, Jenkins and Android development, here’s the 2023 Java roadmap for developers to follow.

Roadmap for Java

Here are the steps you’ll want to follow on the 2023 Java developer career roadmap:

  1. Learn the fundamentals.

  2. Get object-oriented.

  3. Install the JDK and an IDE.

  4. Dig deeper into the API.

  5. Build out your core Java skills.

  6. Master collections.

  7. Get Functional.

  8. Straddle the middle-tier.

  9. Learn Java DevOps tooling.

  10. Study the JVM and the Java platform.

Learn the fundamentals of Java

At their core, all programming languages are the same.

All a computer program can really do is:

  • Manage data through the declaration of variables.

  • Perform conditional logic with if … else statements.

  • Do all of this repeatedly and fast with iterative loops.

Your first stop on the Java developer’s roadmap is to learn these fundamentals.

Learn Java fast

It’s easy to get started with Java.

You don’t even have to install an IDE or the JDK. You can learn the basics of Java online with sites like Onecompiler and Replit.

You can make learning Java even easier if you use JShell.

It’s much easier to learn Java through the JShell scripting environment than by creating Java apps with the intimidating public static void main method declaration in them. JShell will make your learning journey much easier.

Once you’re set up on Replit or Onecompiler, create some basic applications that force you to learn loops, conditional logic and variable declarations. Popular projects that drive the learning include:

  • The number guesser.

  • Rock paper scissors.

  • A to-do list.

  • A simple calculator.

When you’ve got the fundamentals under your belt, you’re ready to learn about object-oriented analysis and design.

Object-oriented programming concepts

In terms of loops, variables and conditional statements all programming languages are pretty much the same. Where programming languages differ is how they organize data.

Java is an object-oriented programming language, which means it organizes data into components known as objects. That means the next stop on the 2023 Java developer’s roadmap is to learn object-oriented analysis and design.

Java object-oriented analysis and design concepts

In Java, object-oriented programming means you organize your data into several categories:

  • Classes.

  • Interfaces.

  • Enumerations.

  • Records.

To really understand how objects work, you’ll also want to learn how to apply object-oriented concepts such as:

  • Abstraction.

  • Encapsulation.

  • Inheritance.

  • Composition.

  • Polymorphism.

With these components and concepts under your belt, you’ll be an object-oriented expert.
