Introduction

TheW3Schools Java Tutorial is comprehensive and beginner-friendly.

It will give you a fundamental knowledge of Java.

It is designed for beginners and requires no prior experience with programming.

The content has been carefully made to be bite-sized, simple, and easy to understand.

The content has been proven by millions of users over the years. It is updated and improved frequently.

The syllabus outline and its sequence are structured so you can learn Java step by step, from the introduction to creating your first application with Java.

Learning Outcomes

  • Understand Java and set up a development environment.
  • Learn the foundations of Java such as Java syntax, variables, data types, and operators.
  • Use control structures (If, for, while loops).
  • Understand and apply object-oriented programming (OOP) concepts: classes, objects, and inheritance.
  • Create and use methods for modular programming.
  • Handle exceptions and write error-handling code.
  • Work with Java collections like ArrayList and HashMap.
  • Write and run Java programs.

Note: Are you a teacher teaching Java?W3Schools Academy is a toolbox of features that can help you teach. It offers classroom features such as pre-built study plans, classroom administration and much more. Read more aboutAcademy here.

Overview of the Modules

Get Started


Sandbox and Lab Environment

Java, like any other coding language, is best learned by working hands-on with code.

Easily try code with our "Try it Yourself" editor.

Here, you can edit Java code and view the result.

Example

public class Main {  public static void main(String[] args) {    System.out.println("Hello World");  }}

Try it Yourself »

If you want to explore more and host your project, we have a feature calledSpaces that allows you to build, test and deploy Java code and other backend languages.

Here you get a secure sandbox environment called Spaces, where you can practice coding and test projects in real-time.

Spaces allow you to test, build, and deploy code. This includes a W3Schools subdomain, hosting, and secure SSL certificates.

Spaces require no installation and run directly in the browser.

Features include:

  • Collaboration
  • File navigator
  • Terminal & log
  • Package manager
  • Database
  • Environment manager
  • Analytics
Dynamic Spaces

Java Certification

W3Schools offers an end-of-pathway certification program.

Here you can take exams to get certified.

The Java exam is a test that summarizes the W3Schools Java syllabus.

After passing the exam you get the "Certified Java Developer" Certification.

There are two different types of certifications:

  • Non-adaptive
  • Adaptive

The non-adaptive is pass or no pass.

The adaptive certification is adaptive and graded; students will get a grade from intermediate, advanced to professional.
