How to invoke a method in java using reflection

Question

How can I invoke a method with parameters using reflection ?

I want to specify the values of those parameters.

Answer 1

this is the easiest way I know of, it needs to be surrounded with try & catch:

Method m = .class.getDeclaredMethod("", arg_1.class, arg_2.class, ... arg_n.class); result = () m.invoke(null,(Object) arg_1, (Object) arg_2 ... (Object) arg_n);

this is for invoking a static method, if you want to invoke a non static method, you need to replace the first argument of m.invoke() from null to the object the underlying method is invoked from.

don't forget to add an import to java.lang.reflect.*;
