Java source code is compiled and translated into Java **bytecode**.JRE can be used when a user has to use Java applications but does not do development. It is the most common environment for devices running Java applications.Java Runtime Environment (JRE) is an open source software distribution with a Java class library, specific tools, and a JVM.To understand what we need to install JVM, JRE or JDK, let's understand these terms. JVM, JRE, and JDK are different software bundles available for running java programs with different functionalities. Which One do I need: JVM or a JRE, or a JDK? Here, we will see detailed steps of installation of JDK SE 16 on the Linux operating system. JDK can be installed on different operating systems, including Linux, windows, and macOS. JDK contains tools required for development, and JRE(Java Runtime Environment), which contains all libraries and JVM(Java Virtual Machine), is required to execute the programs. To run any code and develop applications in java language, we need to install Java Development Kit(JDK). Since Java has a runtime environment (JRE) and API, it is called a platform. Any hardware or software environment in which a program runs is known as a platform. Developed by James Gosling at Sun Microsystems that was released in 1995. Java is a high-level, robust programming language and a platform. IDE(Integrated development environment) like Eclipse and IntelliJ makes coding and developing complex projects easier with its user interfaces, automation tool, debugger, and many other features. JDK (Java Development Kit)' is the complete environment required to run java codes on any system. To execute code in any programming language, we need to set up required environments like code editors, interpreters, compilers, and IDEs. Java is one of the most widely used programming languages.
