JAVA: sorting 2 arrays based on 1 array

hi, in my java program there are 2 arrays like-

int[] num = {3,5,1,7,2};
String[] name = {"jo", "sam", "jo", "tom", "rach"};

each arrays have same length & in a specific order

now if I sort num array using Arrays.sort(num) it only sort num array, name array remain unchanged. Same way Arrays.sort(name)...

the out put of the above array is like this:

3 = jo
5 = sam
1 = jo
7 = tom
2 = rach


now I want a code, so when I sort by "num" array (name array will automatic be sorted), output shud be like this

1 = jo
2 = rach

3 = jo
5 = sam
7 = tom



then again, when I sort by "name" array (num will be sorted automatically) output-

1 = jo

3 = jo
2 = rach
5 = sam
7 = tom

how can I do it?
plz someone help

 

You should use a Map which correlates a key(the num) with the value (the string), which is pretty much what you want as far as i understand.
