How do I invoke a Java method when given the method name as a string?

Question

If I have two variables:

Object obj;
String methodName = \"getName\";

Without knowing the class of obj, how can I call the met

Answer 1

Method method = someVariable.class.getMethod(SomeClass);
String status = (String) method.invoke(method);

SomeClass is the class and someVariable is a variable.
