I'm trying to get my java program to execute a jar file which is located on a USB-drive, and I got the code to find the specific file and it's path already but I can't find anything online about how to run said file.
Can anyone help me or direct me to where I can find how to do this?
To clarify, this is not asking how to open a jar file from the cmd, this is asking how to open a jar file from a different java application. This is somewhat related to: how to run a jar file and running command line in java as it combines both of them.

You need to execute java -jar <fully qualified path for your jar on usb> from your java program by using Runtime or ProcessBuilder class.

Thank you, I didn't realise I needed to use runtime, nor have I ever worked with it (still fairly new to java).
