Java get parameter values through reflection -

i have set of classes similar. i'm using reflection access , invoke choose method below. need able mylist parameter. i've tried using proxies but, i'm beginner java , don't understand how implement , use them.

public int choose(list<object> mylist, object card, object color, state state) {       int answer = -1;       // sort through mylist , set answer index of desired object       return answer; }  

is there better way parameter in java without using aspectj? , if so, provide example?

thanks help.

class state { }  class myclass {     public int choose(list<object> mylist, object card, object color, state state)     {         int answer = -1;         system.out.println("mylist has " + mylist.size() + " elements");         (object o : mylist)         {             system.out.println("element -> " + o);         }         // sort through mylist , set answer index of desired object         return answer;     } }  public static int invokechoose(object obj) throws nosuchmethodexception, invocationtargetexception, illegalaccessexception {     method m = obj.getclass().getdeclaredmethod("choose", list.class, object.class, object.class, state.class);     list<object> somelist = new arraylist<>();     somelist.add(integer.valueof(0));     somelist.add(integer.valueof(1));     somelist.add(integer.valueof(2));     object result = m.invoke(obj, somelist, new object(), new object(), new state());     return ((number)result).intvalue(); }  public static void tryit() {     myclass c = new myclass();     try     {         int result = invokechoose(c);         system.out.println("the result is: " + result);     }     catch (throwable e)     {         e.printstacktrace();     } } 

output:

mylist has 3 elements element -> 0 element -> 1 element -> 2 result is: -1
