For understanding 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 installations 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.
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.
