Sorting an array of strings in reverse alphabetical order in Java
- by Quacky
I've been tasked with turning this code into a reverse sort, but for the life of me cannot figure out how to do it. These are my sort, findlargest and swap methods. I have a feeling I am missing something glaringly obvious here, any help would be really appreciated.
public static void sort(String[] arr)
{
for (int pass = 1; pass < arr.length; pass++)
{
int largestPos = findLargest(arr, arr.length - pass);
if (largestPos != arr.length - pass)
{
swap(arr, largestPos, arr.length - pass);
}
}
}
public static int findLargest(String[] arr, int num)
{
int largestPos = 0;
for (int i = 1; i <= num; i++)
{
if (arr[i].compareToIgnoreCase(arr[largestPos]) > 0)
{
largestPos = i;
}
}
return largestPos;
}
public static void swap(String[] arr, int first, int second)
{
String temp = arr[first];
arr[first] = arr[second];
arr[second] = temp;
}
}
