The JRE is the runtime portion of Java software, which is all you need to run it in your Web browser.
What is runtime Java?
The Java Runtime Environment is a software layer that runs on top of a computer’s operating system, providing additional services specific to Java. The JRE smoothes over the diversity of operating systems, ensuring that Java programs can run on virtually any OS without modification.

Forth is an early example of a language designed to be compiled into intermediate representation code; its runtime system was a virtual machine that interpreted that code.
What is the use of runtime environment?
Runtime environments (RTE for short) act as small operating systems and provide all the functionality necessary for a program to run. This includes interfaces to physical parts of the hardware, user interactions, and software components. A runtime environment loads applications and has them run on a platform.
What is a runtime image?
jlink is a tool that generates a custom Java runtime image that contains only the platform modules that are required for a given application. Such a runtime image acts exactly like the JRE but contains only the modules we picked and the dependencies they need to function.
