With the switch to time-based releases with Java 9 the naming scheme also changed, and Java versions aren’t prefixed with 1.x anymore. Defines an API for supporting distributed transactions in JDBC.

Report a bug or suggest an enhancement For further API reference and developer documentation see the Java SE Documentation, which contains more detailed, developer-targeted descriptions with conceptual overviews, definitions of terms, workarounds, and working code examples. There’s two main feature sets I’d like to mention here, though: Before Java 8, whenever you wanted to instantiate, for example, a new Runnable, you had to write an anonymous inner class like so: With lambdas, the same code looks like this: You also got method references, repeating annotations, default methods for interfaces and a few other language features.

So, even though some distributions (see the "Java Distributions" section) still offer a separate JRE download, there seems to be the trend of offering just a JDK. To develop new Java programs, you needed to download a JDK. Simply leave a comment down below. How to install Java, which version to get, and where to get it from (hint: What a Java distribution is, which ones exist, and what are the differences. So, your program can behave differently/have different classes used when run on Java 8 vs. Java 10, for example. Among them are Azul Zulu, Amazon Corretto as well as SapMachine, to name a few. Optionals got the sorely missed ifPresentOrElse method. A JRE includes, among other things, the Java Virtual Machine (JVM) and the "java" command line tool. OracleJDK, which is a branded, commercial build starting with the license change in 2019. With records, it can now be written like this: Again, this is a preview feature and subject to change in future releases. With the Streams API, you can do the following: Java 9 also was a fairly big release, with a couple of additions: Collections got a couple of new helper methods to easily construct Lists, Sets, and Maps.

Java is special in this regard, as it is extremely backwards compatible. Over a million developers have joined DZone. Some companies have policies to only use LTS versions and rely on their OS vendors to provide them these builds, which takes time. Strings and files got a couple of new methods (not all listed here): Starting with Java 10, you can run Java source files without having to compile them first. First, you need to differentiate between a JRE (Java Runtime Environment) and a JDK (Java Development Kit).

So, Java 8 can also be called 1.8, Java 5 can be called 1.5, etc. In Java 8 you also got functional-style operations for collections, also known as the Stream API. This means that your Java 5 or 8 program is guaranteed to run with a Java 8-14 virtual machine - with a few exceptions you don’t need to worry about for now. In theory, you and I could produce a build from that source code, call it, say, MarcoJDK, and start distributing it.

To re-iterate from the beginning, in 2019, unless you have very specific requirements, go get your jdk.zip (.tar.gz/.msi/.pkg) file from https://adoptopenjdk.net or choose a package provided by your OS vendor. Have a look at the "Java Features 8-13" section below. Java 11 was also a somewhat smaller release, from a developer perspective. Rafael Winterhalter compiled a great list of all available OpenJDK builds, including their OS, architecture, licensing, support and maintenance windows. If you are making sure to use the very latest IDEs, frameworks, and build tools and starting a greenfield project, you can, without hesitation, use Java 11 (LTS) or even the latest Java 13. Java 11 was also a somewhat smaller release, from a developer perspective. Therefore, all you need to do to install Java onto your machine is to unzip your jdk-{5-13}.zip file. 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. Simply leave a comment down below.
