Executable JAR files are the easiest way to assemble Java code into a single file which can be executed. Assuming that you have an executable JAR file with pathname <jar-path>, you should be able to run the below line of code:
java -jar <jar-path>
If the command requires command-line arguments, you should place them after the <jar-path>. As an example:
java -jar <jar-path> argument1 argument2 argument3
