使用反射调用静态方法

Question

My project contains this package : com.XYZcontroller

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

Answer 1

You pass the classes as varargs in the method lookup and the instance, which is null for a static invocation and the arguments in the invocation:

boolean useA = true; // use A or B variant:  
Method m = clazz.getMethod("insert", Context.class, useA ? ModelA.class : ModelB.class);  
m.invoke(null, context, object)

Answer 2

Problem solved:)

ModelA and ModelB implement the same interface, for example Model (not important) , model.getClass() is an important part of his

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

Now i can use this :

Controller.insert(this, myModelA);
Controller.insert(this, myModelB);

Thanks all .
