java初学写一个快排压压惊

之前一直是写c++的，有点怕c++的黑魔法啊看的头疼。正好最近要用java，看了一个下午+晚上的语法，有c++的基础看的快一点，写一个快排试试吧。

package helloworld;import java.util.*;public class Home {public static void main(String[] args) {// TODO Auto-generated method Scanner in = new Scanner(System.in);String content = in.nextLine();String[] numbers = content.trim().replaceAll(" +", " ").split(" ");int[] number = new int[numbers.length];for(int i = 0;i<number.length;++i) {number[i] = Integer.parseInt(numbers[i]);}BinarySort(number,0,number.length - 1);System.out.println(Arrays.toString(number));in.close();}public static void BinarySort(int[] numbers,int begin,int end) {if(begin >= end)return;int m = Merge(numbers,begin,end);BinarySort(numbers,begin,m - 1);BinarySort(numbers,m+1,end);}public static int Merge(int[] numbers,int begin,int end) {int x = numbers[end];int i = begin - 1;for(int y = begin;y<end;++y) {if(numbers[y] <= x) {++i;int tmp = numbers[y];numbers[y] = numbers[i];numbers[i] = tmp;}}int tmp = numbers[i+1];numbers[end] = tmp;numbers[i+1] = x;return i+1;}
}
