given:
    private Integer _size;

    public Integer getSize() {
        return _size;
    }

    public void setSize(Integer size) {
        _size = size;
    }

- User places caret onto declaration of _size and calls Refactoring, change parameter
- Refactoring queries new type by offering an overwritable list of "compatible" types
- User picks or enters new type, e.G. "Long"
--> System replaces the type for all occurencies (declaration, getter, setter and all usages)
