What are the complexities of different sorting algorithms in Java?

Can you explain the time complexities of different sorting algorithms in Java?

Sure! The time complexities vary by algorithm. For example, Bubble Sort has a worst-case complexity of O(n^2), while Quick Sort has an average complexity of O(n log n).

What about space complexity? Are there any algorithms that are more efficient in that regard?

Yes, algorithms like Merge Sort have a space complexity of O(n) due to the temporary arrays used, while Quick Sort is more space-efficient with O(log n) in the average case.

Which sorting algorithm would you recommend for large datasets?

For large datasets, I recommend Quick Sort or Merge Sort due to their efficient average time complexities. However, if stability is required, Merge Sort is a better choice.

Are there any built-in sorting methods in Java?

Yes, Java provides built-in sorting methods like Arrays.sort() and Collections.sort(), which use a dual-pivot Quick Sort algorithm for efficiency.
