Invoke static method using reflection

My project contains this package : com.X.Y.Z.controller

This package includes 3 files

ControllerA.java

 public class ControllerA {
    public static void insert(Context context, ModelA model) {/*do somethings*/}
  }

ControllerB.java

 public class ControllerB {
    public static void insert(Context context, ModelB model) {/*do somethings*/}
  }

MainController.java

I use following code to invoke insert method from Controller A or B it depends on some condition

public static void insert(Context context, Object object) {
  Class<?> clazz = Class.forName(mClass); //Controller A or B
  Method method = clazz.getMethod("insert", ?);
  method.invoke(null, ?);
}

how do i pass arguments ? object may be ModelA or ModelB

I apologize if my wording is not true
