Java Runtime Environment Filehippo, otherwise called Java Runtime, is a piece of the Java Development Kit (JDK) that contains and organizes the arrangement of devices and the least necessities for executing a Java application. The JDK, alongside the Java Virtual Machine (JVM) and the JRE, can be utilized by engineers to program and run Java applications.

In order for a software program to execute code, it needs a Java runtime environment to load class files, verify access to memory and retrieve system resources. The JRE specifically contains a Java class loader, which is responsible for loading classes and connecting them to the core Java class libraries, and the JVM, which ensures proper environment performance.

Java is everywhere! Almost every piece of electronic equipment in the world uses Java technologies. If that’s not impressive, think of billions of PCs, mobile phones, Blu-ray players, printers, medical devices, car navigation systems, webcams or even lottery terminals.


Java 32 and 64 bit enables developers to create software on one platform (Java Platform) and provide it to users running almost any other platform (Windows, Mac, Linux, Solaris or Unix). Java also allows the execution of Web applications and services. Behind this highly customizable and powerful platform stands the Java programming language.

The Java Runtime Environment (JRE) brings the Java platform to your PC within seconds from starting the installation process. While Java sits patiently on the computer, it instantly acts when called upon. And that happens more often than you may think of. Whether you play online games or free video chat with your friends anywhere around the world, Java is running in the background making sure you have an enjoyable experience.

Oracle’s platform also features a Control Panel that can be easily accessed within your computer’s (oh, well!) Control Panel. It allows the configuration of the network and temporary Internet files settings or security certificates. You can also manage the settings of the JRE and access more advanced functions such as Debugging, Java console, Default Java for different web Browsers, Java Plug-in, JavaFX runtime, JRE Auto-Download or Security.

The thing that sits at the core of the Java Platform is the Java Virtual Machine. Its sole purpose is the execution of Java bytecode programs that uses a JIT compiler to translate these programs into instructions while caching the code in memory. This makes Java applications able to run on multiple platforms while having to warm up a bit until the loading process is completed.

Java Runtime Environment:

  • Deployment technologies like Java Web Start and Java Plug-in.
  • User interface toolkits like Java 2D.
  • Integration libraries like Java Database Connectivity (JDBC) and Java Naming and Directory Interface (JNDI).
  • Lang and util libraries like Java Archive (JAR).
  • Other base libraries like Java Management Extensions (JMX), Java Native Interface (JNI) and Java for XML Processing (JAX-WS).
  • Write software on one platform and run it on practically any other platform
  • Create programs to run within a web browser and web services
  • Develop server-side applications for online forums, stores, polls, HTML forms processing, and more
  • Combine Java technology-based applications or services to create highly customized applications or services
  • Write powerful and efficient applications for mobile phones, remote processors, low-cost consumer products, and practically any device with a digital heartbeat

Java Runtime Environment Filehippo Features

Standard libraries supply a generic means to access host-specific features like graphics, threading, and networking. Programming in any computer language simply takes a text editor and understanding of syntax, along with a crystal clear idea about what is you’re attempting to create. Ideally, it is going to occur every time a program is idle. Software development projects searching for a solution combining build tool and dependency management can utilize Ant in conjunction with Apache Ivy.

The way of doing so is based on the edition of Windows you’re using. Otherwise, you’re going to be supplied with an alert instructing you to download an up-to-date edition. The two Java versions are not going to interfere. If you’re running the newest edition of Java, you’re going to be met with a cheery success message. All the most recent version of Java is going to be listed on that page. Before downloading the most recent Java version, you must make sure the old one has been uninstalled.

JRE on your PC

To download JRE on your PC isn’t difficult in any respect. So it is advised you use a system utility software that supplies the feature of the online optimizer. Delete each Facebook application that you don’t require. You can also pick the default app for certain file types or specific protocols from different alternatives. The majority of the time it’s the slow browser that loads web pages slower than that which is expected. Samsung’s users are totally free to work on the Internet so they can easily download Java games. If you’re a standard home user, you may probably do without it.

Programming experience

No prior programming experience is necessary. Garbage collection may occur at any moment. You are going to want an online connection the very first time you launch the game, but after that, you’ll be able to play offline with no problems. Java Web Start is not hard to use. The principal use of ImageJ is it can calculate area and pixel values which might be helpful for graphic designers. To do so you’ll need to adjust internet settings. Yet another distinctive quality of JRE is that it’s also a plugin that lets you observe the entire content on various browsers.

The Java Runtime Environment Filehippo is also meant to be distributed by developers alongside their main Java application. This way, they make sure that you will be able to run their Java-written programs. If you don’t have it by now, you better get it. You’ll be joining an ever-growing number of users that use Java technologies while working on their PCs.

Conclusion: The JRE acts as a software layer on top of the various operating system that enforces uniformity and provides additional Java services, such as automatic memory.
