How would I get the instance of a listener?

[shadow violet]

I am iterating through a list of classes that implement a listener.

Example:
public class Demo implements Listener

On this line here I try to get the instance, but I do not know how.

Listener listener = (Listener) Class.forName(classPath).?????????;

How can I get the instance of this interface?

.getDeclaredConstructor(PARAMETERS).newInstance(ARGUMENTS);

PARAMETERS is just the Classes of all constructor parameters (or leave it out if there are none)

ARGUMENTS refers to the arguments/the actual objects passed to the constructor
