Java 8 was a massive release and you can find a list of all features at the Oracle website. Before Java 8, whenever you wanted to instantiate, for example, a new Runnable, you had to write an anonymous inner class, like so:. You also got method references, repeating annotations, default methods for interfaces, and a few other language features. A quick example:. Streams got a couple of additions, in the form of takeWhile , dropWhile , and iterate methods.
And a couple of other improvements, like an improved try-with-resources statement or diamond operator extensions. Java 9 brought the initial preview version of a new HttpClient. With Java 9, Java got its own, modern client — although this is in preview mode, which means that it is subject to change in later Java versions.
It is not in the scope of this guide to go into full detail on Jigsaw, but have a look at the previous links to learn more. Java 10, for example. There have been a few changes to Java 10, like garbage collection, etc. But the only real change you as a developer will likely see is the introduction of the var keyword, also called local-variable type inference. It is still strongly typed, though, and only applies to variables inside methods thanks, dpash , for pointing that out again.
Starting with Java 10, you can run Java source files without having to compile them first. A step towards scripting. Java 12 got a couple of new features and clean-ups , but the only ones worth mentioning here are Unicode 11 support and a preview of the new switch expression, which you will see covered in the next section.
You can find a complete feature list here , but essentially, you are getting Unicode Switch expressions can now return a value. This article originally appeared on www.
Stephen Colebourne wrote a fantastic article on the different available Java distributions. Thanks, Stephen! Published at DZone with permission of Marco Behler. See the original article here. Thanks for visiting DZone today,. You can find a complete feature list here , but essentially you are getting Unicode Switch expressions can now return a value. There are now record classes, which help alleviate the pain of writing a lot of boilerplate with Java.
Introduced as an experimental feature in Java 13 see above , multiline strings are now production-ready. This means that while the class is public , the only classes allowed to subclass Shape are Circle , Rectangle and Square. The Records and Pattern Matching features from Java 14 see above , are still in preview and not yet finalized.
The Z Garbage Collector is not marked experimental anymore. Now you can pass Objects to switch functions and check for a particular type. Allows you to call native functions and access memory outside the JVM. Since Java 1. How to install Java, which version to get and where to get it from hint: Adoptium.

Java Versions and Features Last updated on October 10, -. TL;DR I only want a download link and know about everything else. Where should I go? What is the latest Java version? What Java version should I use? Why are companies still stuck with Java 8? To name a few:. Why are some Java versions, like 8 also called 1. What is the difference between the Java versions? Should I learn a specific one?
You do not just "learn" a specific Java version, like What are examples of these new features between Java versions? Have a look at the Java Features section. Up until now, we have only been talking about "Java". But what is Java exactly? Highly recommended if you are looking to install Java. Recommendation To re-iterate from the beginning, in , unless you have very specific requirements, go get your jdk. Language Features: Lambdas etc. Now pre-Java 8 you basically had to write for-loops to do something with that list.
Metadata: also called annotations; allows language constructs such as classes and methods to be tagged with additional data, which can then be processed by metadata-aware utilities. Enumerations: the enum keyword creates a typesafe, ordered list of values such as day. Previously this could only be achieved by non-typesafe constant integers or manually constructed classes typesafe enum pattern. Swing: new skinnable look and feel, called synth. Var args: the last parameter of a method can now be declared using a type name followed by three dots e.
Void drawtext string In the calling code any number of parameters of that type can be used and they are then placed in an array to be passed to the method, or alternatively the calling code can pass an array of that type. Enhanced for each loop: the for loop syntax is extended with special syntax for iterating over each member of either an array or any iterable, such as the standard collection classesfix the previously broken semantics of the java memory model, which defines how threads interact through memory.
Automatic stub generation for rmi objects. Static imports concurrency utilities in package java. Scanner class for parsing data from various input streams and buffers. Assertions StringBuilder class in java. Support for older win9x versions dropped. Upgrade of JAXB to version 2. Support for pluggable annotations Many GUI improvements, such as integration of swingworker in the API, table sorting and filtering, and true swing double-buffering eliminating the gray-area effect.
Java se 6 update 10 A major enhancement in terms of end-user usability. Java Deployment Toolkit, a set of javascript functions to ease the deployment of applets and java web start applications. Java Kernel, a small installer including only the most commonly used jre classes. Enhanced updater. Enhanced versioning and pack support: server-side support is no longer required. Java quick starter, to improve cold start-up time. Improved performance of java2D graphics primitives on windows, using direct3D and hardware acceleration.
Next-generation java plug-in: applets now run in a separate process and support many features of web start applications. Incognito Incognito Note that this can be found here: en. I'd preferred a simple link to wikipedia instead of a copy'n'paste — Andreas Dolk.
