You can access all of JRE’s functions and change them according to your requirements. Part of Oracle Technologies, JRE features a Control Panel using which you can configure security certificates, as well as network settings. These include automatic allocation and management of memory, Java Web Start and Plug-in, Java Naming and Directory Interface (JNDI), Java Archive (JAR), and Java for XML Processing (JAX-WS), among others. The primary function of the Java Virtual Machine or JRE is to ensure that Java applications run on different operating systems without requiring any modification.Īpart from this, JRE also consists of a range of components and libraries without which apps wouldn’t function. It offers additional services specific to applications written in Java. Java Runtime Environment is a meta-operating system that sits atop the computer’s operating system. Numerous medical devices, printers, navigation systems, mobile phones, and PCs also make use of Java. Due to platform portability, Java is used to create billions of games, apps, and services. The only requirement is that all devices have JRE installed. For instance, a Java application created on Windows will run, without any glitch whatsoever, on Mac or Linux computers. Using Java, developers can create a software application on one operating system and provide it to users running another OS. This means that Java programs can easily run on a wide range of computers, provided they have the Java Runtime Environment installed. However, the reason behind its popularity lies in the fact that it is platform-independent.
It’s a comparatively new programming language that is fast and secure and allows developers to create modular applications with recyclable code. Some of the most prominent companies in the world, including Airbnb, Uber, LinkedIn, and Spotify use Java to create web and mobile applications. You can’t develop applications with JRE, but need it on your device to run Java programs. Owing to Java’s popularity, a lot of applications, including games, web apps, and services now require Java Runtime Environment to run unhinged. They could call upon JRE for resources, tools, and memory, whenever required. However, with the creation of the Java Runtime Environment, Java programs no longer had to rely on the device’s operating system to execute.
