Dynamic class loading - Java

I am trying to create a program that will look for the specified directory for any other jar files (which I will not know the name). Then it will take an object from this file and create an instance that can be specified later in my program.

I am happy to do research on how to do this on my own, but I don’t know how it will be caused, even to start looking.

Can anyone point me in the right direction? Thanks
