Sorting two arrays simultaneously

Question

I\'m learning and understanding Java now, and while practising with arrays I had a doubt. I wrote the following code as an example:

Answer 1

You have to ZIP your two arrays into an array which elements are instances of a class like:

class NameNumber 
{

    public NameNumber(String name, int n) {
        this.name = name;
        this.number = n;
    }

    public String name;
    public int number;
}  

And sort that array with a custom comparator.

Your code should be something like:

NameNumber [] zip = new NameNumber[Math.min(a.length,b.length)];
for(int i = 0; i < zip.length; i++)
{
    zip[i] = new NameNumber(a[i],b[i]);
}

Arrays.sort(zip, new Comparator() {

    @Override
    public int compare(NameNumber o1, NameNumber o2) {
        return Integer.compare(o1.number, o2.number);
    }
});
