Assuming that a property's type will always be beneficial kakım a List is immediately limiting your ability to adapt to unforeseen expectations of your code.Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.Interface’ler karşı hen
