I have a package with class files like this:

ClassA.java
ClassB.java
ClassC.java
...
App.java

App.java contains a main function which needs to instantiate an object depending on a given string with a value "ClassX" matching one of the CLass...java classes.

How can I instantiate that class?

I assume you are familiar with conditional statements? – Stultuske Sep 04 '20 at 06:51

@Stultuske I probably didn't make it clear enough: I do not want to write conditionals for all the possible classes, but want to use the string value to instantiate the class. – halloleo Sep 04 '20 at 06:55
@Vladimir That looks pretty good. Thanks! :-) – halloleo Sep 04 '20 at 06:55
