数组—排序

代码：

package lss;
import java.util.*;

public class Pailie {

public static void main(String[] args) {    int k;    int s[] = {9,8,7,6,4,5,3,2,1,9,8};    int baka[] = new int[11];    System.out.println("排列前a数组各元素为：");    for (k = 0; k < s.length; k++) {//输出s        System.out.print(s[k] + "\t");        baka[k] = s[k];//把s的值赋给baka    }    System.out.println();    Arrays.sort(s);//对s进行排列    System.out.println("排列后a数组各元素为：");    for (k = 0; k < s.length; k++) {        System.out.print(s[k] + "\t");    }    System.out.println();    for (k = 0; k < baka.length; k++) {        s[k] = baka[k];//把baka（原始数）赋给s    }    Arrays.sort(s, 3, 8);//对s的3-7个排列    System.out.println("部分排列后各元素为：");    for (k = 0; k < s.length; k++) {        System.out.print(s[k] + "\t");    }    System.out.println();}}
