Is it possible to call a method by its name?

Question

Java

Is it possible in Java to call a method by its name or by some key? The situation is this. I am reading a method name from a file (as well as the parameters to pass those to the method) and I need to call it. The question is, can this be done, and if so, how?

Answer 1

Can!

Class<?> c = Class.forName("class name");
Method  method = c.getDeclaredMethod ("method name", parameterTypes)
method.invoke (objectToInvokeOn, params)
