There are stand-alone programs which can be executed e.g. under Windows, of which the developers state that they wrote the program "using the Java programming language". I am not a Software developer or a programmer, but through some basic programming courses in school and at university I was taught that Java Programms can only be run in a Java Runtime Environment (JRE).

So what I am asking is: how can I run these programs written in Java on my computer, without having any JRE?

A follow-up question would be: How is this step technically performed, to create such a program that does not need a JRE for running from Java code?

Please note: I am not questioning the concept of the JRE as a whole. It does make sence to me to use this concept, to have platform independent programs by using a runtime environment. My question solely is about how is this stand-alone solution made possible, not about its convenience, or its meaningfulness. It is obviously done for whatever reasons, and I want to know how.

    I guess those programs are being shipped with bundled JRE. – Crozin Nov 27 '15 at 11:48

    I have created a list of ways to [deploy Java applications here](http://stackoverflow.com/questions/1453369/i-have-never-seen-a-software-be-released-as-jar-so-how-can-i-make-a-software-be/1453477#1453477). This includes ways to deploy as "JVM-less" executables. – Michael Lloyd Lee mlk Nov 27 '15 at 12:04

You can Ship JRE with your application. Then application will use it for execution. There are also some Compilers for this purpose. Read this question: running a java program as an exe in windows without JRE installed

You can use Excelsior JET compiler for that purpose.It will convert your java application to .exe

See Excelsior for more information on this.
