Hy ,what i`m trying to do is something like this: private class aClass { private ArrayList idProd;

aClass(ArrayList prd) { this.idProd=new ArrayList(prd); }

public ArrayList getIdProd() { return this.idProd;

} }

So if i have multiple instances of ArrayLIst (st1 ,st2 ,st3) and I want to make new objects of aClass : { aClass obj1,obj2,obj3; obj1=new aClass(st1); obj2=new aClass(st2); obj3=new aClass(st3); }why all of the aClass objects will return st3 if I access the method getIdProd() for each of them(obj1..obj3)? is an arraylist as a instance variable automatically declared static?
