The latest available version is compatible with older versions. However, some Java applications (or applets) can indicate that they are dependent on a particular version, and may not run if you do not have that version installed.
The open-source variant is free to use in production, while there is a fee for organizations using the commercially licensed JDK in production. If you want long-term support from Oracle for a Java release you have to pay for it by using the Oracle JDK build.
Java SE 8 remains the preferred production standard in 2019. While both 9 and 10 have been released, neither will be offering LTS. Since it's first release in 1996, Java has maintained a reputation for being one of the most secure, reliable, and platform independent languages for computer programming.
The first version was released on January 23, 1996. The first stable version, JDK 1.0.2, is called Java 1.

The Java EE platform is built on top of the Java SE platform. The Java EE platform provides an API and runtime environment for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.
Using Java in Oracle DatabaseYou can write and load Java applications within the database because it is a safe language with a lot of security features. Java has been developed to prevent anyone from tampering with the operating system where the Java code resides in.
But is Java hard to learn? The simple answer is that yes, it can be tricky. As you learn Java programming, you'll encounter some simple concepts like variables and functions, but there are also more abstract, complex ones like objects, bringing inheritance, and polymorphism that can be difficult to understand.
What about the Java license costs?
| Products & Metrics | Named User Plus (NUP) | Software Update (License & Support) |
|---|
| Java SE Advanced Desktop | $40 | $8.80 |
| Java SE Advanced | $100 | $22.00 |
| Java SE Suite | $300 | $66.00 |
You only need Java if an app requires it. The app will prompt you. So, yes, you can uninstall it and it's likely safer if you do.
Oracle's JDK (commercial) – you can use this in development and testing for free, but if you use it in production you have to pay for it. Oracle's OpenJDK (open source) – you can use this for free in any environment, like any open source library.
YES. Java is one of the most secure languages in the market. Java's security features are far superior to other leading programming languages. However, java applications are at higher risk because of their ubiquitous nature.
Oracle JDK and OpenJDK builds from OracleBeginning with Java SE 11 (September 2018, LTS), not only does Oracle provide releases for free for all users under an open source license, but Oracle also provides releases which are commercially supported and included for use with Oracle products.
Yes, Java (and the JDK) is safe. The older Java browser plugin had security issues, but most browsers no longer support plugins like that anymore.
Java has been on the decline for a number of years. If you look at the TIOBE index from the mid to late part of this decade it has been losing percentage points. From May 2016 to May 2017, for example, the language declined 6% – this indicates that it's losing mindshare to other languages.
What is the cost of a Java SE Subscription? Desktop pricing is $2.50 per user per month, or lower with tiered volume discounts. Processor pricing for use on Servers and/or Cloud deployments is $25.00 per month or lower.
JDK 11 is the open-source reference implementation of version 11 of the Java SE Platform as specified by by JSR 384 in the Java Community Process. JDK 11 reached General Availability on 25 September 2018.
In 2014, Oracle introduced a new desktop license - Java SE Advanced Desktop. Oracle has announced that from January 2019, Java SE 8 public updates will no longer be available for business, commercial or production use without a commercial license although it will remain free for general purpose computing usage.
JRE = Java Runtime Environment (users need this, this is every computer user today) Java SE = Java Standard Edition.
The biggest difference between OpenJDK and Oracle JDK is licensing. OpenJDK is completely open source Java with a GNU General Public License. Oracle JDK requires a commercial license under Oracle Binary Code License Agreement.
The most significant benefit of the Java language is that it is open-source and has a big and strong community of developers. Thus, many great frameworks were built on the basis of Java for the development of web applications, network applications, ORM, etc.
We don't provide a separate JRE download with JDK 11. Instead, you can use jlink to create a custom runtime image with just the set of modules required by your application. Please see for details. AdoptOpenJDK offers JRE downloads for Java 8 and up.
But third and most important, earlier in that very roadmap document, the definition of "commercial user" is made clear: "Commercial Users are entities other than Oracle Customers that use Java SE for free for business, commercial or production purposes as part of a Java application delivered by a third party or
