What is the best sorting algorithm in Java?

What is the best sorting algorithm in Java?

The best sorting algorithm in Java depends on the use case. For general purposes, QuickSort is often preferred due to its average-case efficiency.

What about for small datasets?

For small datasets, Insertion Sort can be very efficient because of its low overhead and simplicity.

Are there any built-in sorting methods in Java?

Yes, Java provides the Arrays.sort() method for arrays and Collections.sort() for lists, which use a dual-pivot QuickSort.

Can you explain how QuickSort works?

Sure! QuickSort works by selecting a 'pivot' element and partitioning the array into two sub-arrays, then recursively sorting the sub-arrays.
