Create a program that is usable in Windows

  

Based on a fairly simple example: create a calculator. After having the code, how do I create an application that can be run in Windows, a so-called "program"?

cd src
dir /s /B *.java > ../sources.txt
cd ..
javac -encoding utf8 -d bin @sources.txt
jar -cfe calculadora.jar com.example.Calculadora -C bin .

If you want to compile in unix / linux, even if you go (or not) use the JAR produced in windows, you can do so (changing only the second line):

cd src
find -name "*.java" > ../sources.txt
cd ..
javac -encoding utf8 -d bin @sources.txt
jar -cfe calculadora.jar com.example.Calculadora -C bin .

To run it in an environment (unix / linux or windows) where a compatible JVM is installed properly , you can double-click on the file calculadora.jar or do this:

java -jar calculadora.jar

Programs created in the Java language run on the Virtual Java machine, so they are not stand-alone, they depend on the user having JavaVM installed, it is impossible to run a program written in Java without this.

Compiling a program in C, C ++, etc, will be compiled based on the compiler used, there is no way to run in Windows something that was compiled for Linux, just like it does not have to run something that was compiled for Mac OS X v10.1 run on Mac OS X v10.13 , this is due to the architecture used by both operating systems.

Compiling in Windows generally has compatibility between Windows systems, but depends heavily on the compiler you used and the APIs used to write the code.

So to summarize, if it's Java will run on multiple systems as long as it has JavaVM installed, if C is going to have to compile in architecture by architecture you want to run the program.

Linux generally does not have compatibility between different Linux distros, so some applications are usually distributed in sources and you have to compile with GCC (or other compiler that the distro and / or repositories have), of course there are no guarantees of depends on who wrote the code.
