There are different ways to sort things, and in this article, we will learn how to use three popular sorting methods in Java: Bubble Sort, Merge Sort, and Quick Sort. We will explain these methods step by step i
快速排序法: public class Main { public static void main(String[] args) { int a[]={7,8,1,3,5}; new Main(a); } public Main(int[] a){ ...

Antiquicksort.The algorithm for sorting primitive types in Java is a variant of 3-way quicksort developed byBentley and McIlroy. It is extremely efficient for most inputs that arise in practice, including inputs that are already sorted. However, using a clever technique described by M. D....
