Java equivalent of C# Sorted List [duplicate]

sorted collection in java

I was wondering if Java has its own version of Sorted List, or if I need to create my own. I want the list to automatically update itself if something is removed. For example, if I remove something from the start of the list, or even in the middle, I want everything behind it to move up in the list, and the remaining null value space to be removed.

If you're really after the equivalent of a .NET SortedList, which is actually a map ordered by its keys, then the closest equivalent is probably TreeMap. That's actually more like SortedDictionary than SortedList, given that it's a tree rather than just a list, but it's probably the closest available option.

However, what you've described is more like ArrayList, which is similar to .NET's List<T>.
