Java Question

I am looking to do an ascending sort 7 arrays, based of a the values of one of them and then print the final array using a loop inside of a method. the array values are entered by the user and will contain at least one set of data but no more than 5 sets.

My code so far is below, its the basic structure of a selection sort as I was requested to use that, I am looking to do the ascending sort off of the array simp (stands for simple interest) but I cannot figure out how to get all the other arrays to move with it retain the values.

any ideas on the loop method to use for this?

`public static void sort(double[] amount, double[] iRate, int[] term, double[] simp, double[] month, double[] daily, double[] weekly)`

{

for (int i=0;i<simp.length-1;i++)

{

int minindex=i;

for (int j=i+1;j<simp.length;j++)

{

if(simp[minindex]>simp[j])

minindex=j;

}

double temp = simp[minindex];

simp[minindex]=simp[i];

simp[i]= temp;

}

}

`[Line #] [Principal Amount] Interest rate term simple monthly weekly daily`

1 $1,375.00 1.18% 7 9.4244 9.4522 9.4557 9.4567

2 $100.00 3.25% 6 1.625 1.636 1.6377 1.6382

3 $100.00 3.25% 12 3.25 3.2988 3.3023 3.3032

[Line #] [Principal Amount] Interest rate term simple monthly weekly daily

1 $100.00 3.25% 6 1.62 1.636 1.6377 1.6382

2 $100.00 3.25% 12 3.25 3.2988 3.3023 3.3032

3 $1,375.00 1.18% 7 9.4244 9.4522 9.4557 9.4567

One straightforward way to do it using your existing code is to swap elements in all arrays whenever you are swapping elements in `simp`

:

```
double temp = simp[minindex];
simp[minindex]=simp[i];
simp[i]= temp;
temp = iRate[minindex];
iRate[minindex]=iRate[i];
iRate[i]= temp;
.
.
.
```

This isn't the most elegant way. The OO way to do it would be to have an object that has `amount, iRate, term...`

as members and sort an array of these objects.
