Generic List setter ?

It's possible to have a method that not matter what kind of list you send, it would set it to the corresponding variable ? ex.

List<Foo> foo = new ArrayList();
List<Bar> bar =  new ArrayList();

public <T> void setList(List<T> myList){
    if(myList instanceof List<Foo>) this.foo = myList;
    if(myList instanceof List<Bar>) this.bar = myList;
}

List<Foo> foo = new ArrayList();
List<Bar> bar =  new ArrayList();

public <T> void setList(List<T> myList){
    if(myList instanceof List<Foo>) this.foo = myList;
    if(myList instanceof List<Bar>) this.bar = myList;
}
