Question

Working on a requirement where i need to call a class Method based on the name of the class and method being provided at runtime.

What are the different way by which i can achieve this (preferred one).One issue which i can see is that there can be multiple classes with same name so that can create a problem.

Any inputs how best this can be done will be much helpful for me

Thanks in advance

Answer 1

You have to use the fully qualified class name with its package, which is unique for a ClassLoader.

Class clazz = Class.forName(packageAndClassName);
Method method = clazz.getDeclaredMethod(methodName, parameterTypes);

You need to know the parameters types otherwise you can’t give it sensible values when you call it.
