JDK 9 is the latest version of the Oracle Java Development Kit. Java SE 9 is coming with some improvements in Process API. They have added couple new classes and methods to ease the controlling and managing of OS processes. Like any other software, Java also comes with many different versions as it develops and gets improved, with new features getting added in every major upgrade. Some new methods are added to the java.awt.Desktop class. Prior to this release, on Windows and Linux, Java applications were sized and rendered based on pixels, even on HiDPI displays that can have pixel densities two to three times as high as traditional displays.
Installing this update will ensure that your Java applications continue to run as safely and efficiently as always. The Java Platform lets you develop and deploy Java applications on desktops and servers, as well as in today’s demanding embedded environments. For current Java releases, please consult the Oracle Software Download page. Downloading these releases requires an oracle.com account.
Advantages of Java SE 9 Module System
HTTP 2 Client − new HTTPClient API supporting websockets and HTTP 2 streams and server push features. Java is currently owned by the Oracle Corporation which acquired Sun Microsystems in 2010. Following tutorial will show you how to setup and configure Java 1.9 on Windows so you can develop and run Java code. The Oracle JDK 9 includes both Java runtime environment and javac compiler. For a new “greenfield” project, Java 11 is most probably the best choice by now. But it might be necessary to stick with Java 8 if the toolchain to be used does not fully support Java 11 yet. They are going to introduce new HTTP 2 Client API under “java.net.http” package.
- In Java 9, JDK itself has divided into set of modules to make it more lightweight.
- There is no Strong Encapsulation in the current Java System because “public” access modifier is too open.
- In this section, we will discuss “Why we need Java SE 9 Module System” that means the problems of Current Java System.
- In this tutorial, we will discuss all the main features that are given below.
- Like any other software, Java also comes with many different versions as it develops and gets improved, with new features getting added in every major upgrade.
Up until then, Java’s built-in Http support was rather low-level, and you had to fall back on using third-party libraries like Apache HttpClient or OkHttp (which are great libraries, btw!). Streams got a couple of additions, in the form of takeWhile,dropWhile,iterate methods. Collections got a couple of new helper methods, to easily construct Lists, Sets and Maps. One of the vendors who builds Java from source is Oracle. This leads to two different Java distributions, which can be very confusing at first.
