我要按分数排序，怎么做？

[解决办法]

Java code

public class ArrSort {    public static void main(String[] args){        int[] arrInt = {4, 2, 3, 1, 6};        String[] arrStr = {"ab", "cd", "ef", "gh", "ij"};        int tmpInt;        String tmpStr;        for(int i = 0; i < arrInt.length - 1; ++i){            for(int j = 0; j < arrInt.length - i - 1; ++j){                if(arrInt[j] > arrInt[j+1]){                    tmpInt = arrInt[j];                    arrInt[j] = arrInt[j+1];                    arrInt[j+1] = tmpInt;                    tmpStr = arrStr[j];                    arrStr[j] = arrStr[j+1];                    arrStr[j+1] = tmpStr;                }            }        }        for(int i = 0; i < arrInt.length; ++i){            System.out.println(arrInt[i] + "------" + arrStr[i]);        }    }}1------gh2------cd3------ef4------ab6------ij这个用JAVA写的arrInt = {4,      2,    3,    1,    6};arrStr = {"ab", "cd", "ef", "gh", "ij"};这两个数组上下的数据是一起的,排序之后仍然能对上号
