Question

I have an unsorted array of objects. I need to know how I can sort my array in descending order, according to the highest value inside the objects.

I need to do this using for loops, not the easy way.

I had done this but it seems there is a problem:

student[] temp=new student[s.length];

for (int i=0;i<s.length;i++)
{
    if (s[i].GetGpa() > s[i + 1].GetGpa())
    {
        temp[i] = s[i];
    }
}

How should I do it using for loops?

Answer 1

This should get you started. You’ll need to create your own Comparator and then call Collections.Sort().

Collections.sort(List<T> list, Comparator<? super T> c)
