Can TreeSet store null values?
An example of an AI chatbot conversation about TreeSet and null values in Java.
Can a TreeSet in Java store null values?
No, a TreeSet cannot store null values because it uses a comparator to order its elements, and null would cause a NullPointerException.
What happens if I try to add a null value to a TreeSet?
If you try to add a null value, it will throw a NullPointerException at runtime.
Is there a way to store null values in a sorted collection?
You can use a HashSet or a List if you need to store null values, but they won't maintain a sorted order.
What are the alternatives to TreeSet for sorted collections?
Alternatives include PriorityQueue, NavigableSet, or using a List with manual sorting.
