The Java Tutorials are practical guides for programmers who want to use the Java programming language to create applications. They include hundreds of complete, working examples, and dozens of lessons. Groups of related lessons are organized into "trails".

The Java Tutorials primarily describe features in Java SE 7.

What's New in javaEdit

The Java Tutorials are continuously updated to keep up with changes to the Java Platform and to incorporate feedback from our readers. Apart from fixing typos and errors, this update includes the following:

  • Lambda expressions, a result of the work of Project Lambda, are a feature being added to the JDK 8 release of the Java platform. Lambda expressions support programming in a multicore environment by adding closures and related features to the Java language. An early access page on Lambda Expressions is part of this tutorial release. As part of this work, the information on Nested Classes, Anonymous Classes, and Local Classes have been updated and a new page on When to Use Nested Classes, Local Classes, Anonymous Classes, and Lambda Expressions has been added. All of this new material is available online only.
  • The Annotations page has been moved and expanded to be a full Annotations lesson. The new lesson includes information on Java SE 8 features: Type Annotations, which can be used in conjunction with pluggable type systems for improved type checking, and Repeating Annotations. This early access lesson is available online only.
  • The lesson Service Providers for Internationalization includes the new section Installing a Custom Resource Bundle as an Extension, which shows you how to load resource bundles with service provider interfaces (SPIs). These interfaces enable you to create applications that you can extend, through plug-ins or modules, without modifying their original code base. See the new section Creating Extensible Applications for more information. These new pages are currently available online only.
