As a means of providing comprehensive details about the relevant Java Runtime Environment (JRE) for Java 14, consider the table outlined below:
html
| JRE Version | Support for Java 14 | Benefit | Disadvantage |
|---|---|---|---|
| JRE 14 | Yes | Implementation of latest features and improvements of Java 14 | No long term support (LTS) |
| JRE 13 | No | Familiar for those who haven’t upgraded to JRE 14 | Incompatible with Java 14 |
| JRE 11(LTS) | No | Long term support guaranteed by Oracle | Does not incorporate new features introduced in Java 14 |
Dimming light over the specifics, `JRE 14` is crucial when your focus scales towards leveraging the most recent features of Java 14. These would indeed be absent in previous versions like `JRE 13` or `JRE 11`. However, it’s important to remember that JRE 14 does not come with long-term-support (LTS), a trait that you might find in JRE 11.
For projects that don’t require up-to-date functionality but need steadfast continuation, then JRE 11 could be a viable choice. On the contrary, if one still employs Java 13, upgrading to JRE 14 can pose compatibility issues thus, JRE 13 remains ideal for them. According to Kent Beck, “Optimism is an occupational hazard of programming; feedback is the treatment.” So while choosing a JRE, feedback from the developers working on the project should ideally also be taken into consideration besides just looking at the benefits and drawbacks.
The concept of JRE illuminates with James Gosling’s words where he stated, “In the world of programming languages, Java has secured its own empire due to 3 things: reliability, security, and ease of use.”
The selection of the right JRE is vital and depends substantially on the specific needs of your project; whether it necessitates the usage of the latest language features or demands long-term support. Therefore, choose wisely to ensure that the JRE aligns with the project requirements.
Exploring the Specifics of JRE for Java 14
Java Runtime Environment (JRE) plays a critical role in executing Java applications as it contains libraries, the Java Virtual Machine (JVM), and other components essential for running compiled Java code. Albeit, to comprehend the specifics of JRE for Java 14, we should first unravel what JRE encapsulates:
-
- Java Virtual Machine (JVM): This is the heart of the JRE that does the bulk work of running your Java coding programs or applications.
-
- Java Class Library: Also referred to as the JCL, this integrated library supports the JVM with an extensive collection of pre-built utility functions.
-
- Runtime Libraries: These are additional libraries and resources used by the JVM when executing Java applications.
The introduction of modules in Java 9 brought about significant changes in the JRE structure. Starting from Java 11, Oracle stopped releasing standalone JREs, meaning developers intending to run Java applications would require JDK. It happened due to the “jlink” tool which lets you create custom runtime images containing only the modules your app needs along with the JVM.
public class Main {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
Analyzing this scenario through the lens of Java 14 makes things more intriguing because of its new features and enhancements. For instance, it offers Helpful NullPointerexceptions feature which is aimed at enhancing the usability of NullPointerExceptions generated by the JVM by describing precisely which variable was null.
Moreover, matching the Java Development Kit (JDK) with the corresponding version of the JRE becomes vital if we consider the pace of feature release facilitated by the six-month release cadence defined by Oracle for Java. Consequently, developers using Java 14 should use the integrated JRE present within the Java 14 JDK for proper compatibility with the new features.
As per Bill Gates, “The advance of technology is based on making it fit in so that you don’t really even notice it, so it’s part of everyday life.” In the context of JRE and Java, it integrates seamlessly into our systems allowing us to power a plethora of applications without consciously acknowledging its existence most of the time.
Therefore, if Java 14 or any future release is your development framework, utilize the built-in JRE that aligns with the JDK version to ensure optimum performance, compatibility, and access to new enhancements.
Understanding Compatibility between Different JRE Versions and Java 14
Certain aspects must be well-understood in relation to the compatibility between different Java Runtime Environment (JRE) versions and Java 14, especially on deciding which JRE should be used for applications developed using Java 14.
Factors to consider when choosing a JRE version for Java 14
- Backward Compatibility: Java is generally known for its robust backward compatibility feature. This means that Java 14-based programs can run on later JRE versions without showing any operational issues and errors.
- Consolidating Libraries/Modules: Starting from Java 9, certain standard Java SE APIs have been encapsulated into modules to improve the platform’s structure. Thus, it is important to ensure that your application does not directly access such APIs or is compatible with this level of modularization if you want to run it on later JREs.
- Deprecation and Removal of APIs: Higher JRE versions might deprecate or completely remove some APIs. As such, your Java 14 code should not depend heavily on certain APIs that are deprecated or removed in later JRE versions. For instance, the `java.security.acl` package was deprecated in Java 14 and removed in Java 15.
// Deprecated API example in Java 14 java.security.acl.Acl;
The official documentation for each release clearly marks the deprecated APIs and those being targeted for removal. So, diligent reading of these documents prior to [upgrading JRE versions](https://www.oracle.com/java/technologies/javase/jdk14-archive-downloads.html#license-lightbox) is highly recommended.
Suggestion on the best JRE for Java 14
Given the points above, using a corresponding or identical JRE version is a sound practice when deploying any Java program to avoid unexpected troubles with backward compatibility or use of deprecated/removed APIs. Hence, if you are developing apps using Java 14, the same version- Java 14 JRE is the optimal choice.
Furthermore, Allan Jacobs, a prominent Java Community Process (JCP) member, once stated, “Despite Java’s strong backward compatibility, using correspondent JRE minimizes the risk of facing unexpected runtime exceptions.”
Indeed, the benefits of matchless API utilization, full security updates, and enhanced performance optimization all become more pronounced when using the matching JRE. In short, when considering which JRE to use for Java 14, focus less on other JRE versions and focus more on the undeniably beneficial functionalities of the JRE version designed specifically for Java 14, remarkably strengthening the development process.
Tips on Selecting the Right JRE Version for Your Java 14 Project
Choosing the correct Java Runtime Environment (JRE) version for your Java 14 project is a significant undertaking that requires deliberate, careful consideration. Understanding the differences between JRE versions and their compatibility with the Java Development Kit (JDK) version of your project is crucial.
Java were historically published in two parts: the Java Development Kit (JDK) and the Java Runtime Environment (JRE). The JDK contains everything necessary to build and run Java programs whereas the JRE, a subset of the JDK, only includes elements necessary to run Java programs. However, beginning with the release of Java 11, Oracle moved to a Long Term Support (LTS) model and stopped issuing separate JRE distributions, now released bundled with the JDK.
This change has implications for those who utilise Java platforms and need only a JRE present. From Java 11 onwards, the JDK distribution will be necessary even if one needs only the functions of the JRE – this presents an important context when selecting the correct JRE for Java 14 projects.
Consideration on Selecting the Right JRE Version
-
- Review Project Requirements: The first step for picking the correct JRE version for a Java 14 project would be to understand the specific needs of the project at hand.
Analyzing the specifics of your project will help you to establish the foundation upon which your decision will lie. Understanding project requirements will enable you to opt for a platform offering the most compatibility and functionality for your Java 14 requirements.
- Evaluate features and abilities of the JRE: Look into the capabilities of the different JRE variants to figure out what fits best for your project.JREs offer varying features and abilities tailored to meet certain prerequisites. For instance, starting from Java 11, LTS versions of Java are released every six months. Thus, it’s essential to always check the latest features/changes made available. Experts recommend going for OpenJDK, an open-source implementation of the Java SE Platform that comes with OpenJ9, an alternate JVM offering lower memory footprint, start-up time, and resource usage.
- Support for JREs: One fundamental factor that can influence your choice of JRE is its support duration.Oracle offers premium support for its editions, while other vendors provide extensive free support. A good practice to get around this challenge is by sticking closely to updates and getting rid of old versions as soon as possible.
As a practical example, let’s say our Java 14 project has high-performance requirements and needs to operate in a resource-constrained environment.
//Our java 14 code
public class HelloWorld {
public static void main(String[] args){
System.out.println("Hello World");
}
}
For such specifications, choosing a JRE that supports efficient runtime performance like AdoptOpenJDK with OpenJ9 might be a wiser option.AdoptOpenJDK provides prebuilt OpenJDK binaries with options for different VMs including HotSpot and OpenJ9, with extensive free support available.
Let’s recall Tim Berners-Lee’s statement about technology. He said, “We need diversity of thought in the world to face the new challenges.” Our choices in technological tools, in this case, JRE versions for our Java 14 projects, should also reflect diverse thinking based on requirements, capabilities, efficiency, and support.
Debunking Common Myths about JRE Usage in Java 14
There is a plethora of myths in the Java community, particularly about Java Runtime Environment (JRE). Given the launch of the new Java Development Kit (JDK) version, Java 14, it has become increasingly important to dispel these misconceptions and provide guidance on which JRE should be used for Java 14.
Myth 1: The JRE can no longer be used after JDK 9
| This is a widely-practiced belief but it’s not entirely correct. Since JDK version 9, there have been changes on how the JRE or runtime environment is delivered and used. Prior to this, the JRE was a standalone component. Since JDK 9, however, Oracle introduced the ‘jlink’ tool, which can create custom runtimes from any set of modules. Therefore, while the standalone JRE has been phased out, applications can still use runtime environments that are even more efficient given they include only necessary parts. |
To exemplify, here is a simple command with
jlink
:
$JAVA_HOME/bin/jlink --module-path $JAVA_HOME/jmods --add-modules java.desktop --output jre
Myth 2: It doesn’t matter what JRE I use because backwards compatibility is guaranteed with Java
This is an oversimplified view on how Java handles backward compatibility. True, Java strives to maintain backward compatibility but this dependency depends on various factors such as deprecated methods, removed APIs and security vulnerabilities. Indeed, it’s essential to use the most recent JRE with Java 14 to harness all its functionalities.
[Oracle JDK vs OpenJDK](https://www.baeldung.com/oracle-jdk-vs-openjdk) highlights comparative analysis between Oracle JDK and OpenJDK.
As per Bill Joy, Co-founder of Sun Microsystems,
“We’ve believed from the very beginning that packaging and distribution are integral parts of the technology. Tying the delivery of enhancements to our operating system has had dramatic impact on the reliability of every release”.
Taking inspiration from Joy’s words, remember that using a JRE compatible with your JDK version is crucial for reliability and efficiency of your Java application. Make an informed decision on what JRE to use by understanding, not necessarily debunking, the myths within the Java community. Keep your knowledge updated and avoid falling for information that misleads or confuses. Standardized practices, like upgrading the JRE with JDK, contribute to the sustained development and growth of Java as a platform and language.
In determining the Java Runtime Environment (JRE) to use for Java 14, several key aspects surrounding your developmental needs and system requirements should be taken into account.
Firstly, Oracle JRE serves as an excellent choice for developers who prioritize consistency and stability. It is widely adopted and supported by a robust user community. Additionally, it provides comprehensive support for all Java libraries and features which makes it a suitable choice for complex Java applications.
Secondly, OpenJDK’s JRE is another viable option, particularly for projects that value open-source tools. This JRE is developed and maintained by the Java developer community, resulting in regular updates and improvements.
Lastly, consider AdoptOpenJDK’s JRE for its high performance and free long-term support. Established by the Java ecosystem, this distribution offers prebuilt OpenJDK binaries which have undergone rigorous testing and quality assurance.
Based on these points, the choice of JRE depends significantly on your specific project requirements.
- If your Java application calls for a commercially-supported runtime with extensive functionalities, then Oracle JRE would be a reliable fit.
- For those favoring open-source solutions enhanced with stringent testing and maintenance, OpenJDK’s JRE could serve as an ideal pick.
- In scenarios where performance and long-term support are pivotal, AdoptOpenJDK’s JRE comes forth as a commendable candidate.
Remember that each JRE version has unique strengths that cater to diverse developmental aspects; therefore, selecting an appropriate one would entail evaluating your application’s prerequisites against each JRE’s capabilities.
