Fetching calling method parameter list (paramter name + value) in the called method

I need to fetch the parameter details of the calling method in the called method at runtime. I cannot directly pass the parameter names. I was wondering if there is any way to achieve this. I have something like this:

public class ABC {
   public void methodOuter(String abc, int xyz) {
         methodInner(); // In this method I need to fetch the methodOuter parameter list details.
   }
}

class XYZ {
   public void methodInner() {
      // Here I need to fetch methodOuter parameter list, i.e I need to get the parameter name 'abc' and its value and parameter name 'xyz' and its value.
   }
}

Any help is appreciated.
