Java equivalent of function mapping in Python

Question

In python, if I have a few functions that I would like to call based on an input, i can do this:

lookup = {\'function1\':function1, \'function2\':function2, \'fu         


        

Answer 1

You could use a Map or Map etc,and then use map.get("function1").invoke(...). But usually these kinds of problems are tackled more cleanly by using polymorphism instead of a lookup.
