How do I remove elements from a TreeSet in Java?

How do I remove elements from a TreeSet in Java?

You can remove elements from a TreeSet using the remove(Object o) method. Just pass the element you want to remove.

What if the element I want to remove doesn't exist in the TreeSet?

If the element doesn't exist, the remove method will simply return false and the TreeSet will remain unchanged.

Can I remove multiple elements at once?

Yes, you can use the removeAll(Collection<?> c) method to remove multiple elements by passing a collection of elements.

Are there any performance considerations when removing elements?

Removing elements from a TreeSet is generally O(log n) due to its underlying red-black tree structure, which is efficient.
