Ignoring case while sorting an array

[mluken]

I have an array that I need to sort alphabetically, however the following sort is case sensitive and I need to ignore case:

java.util.sort(myArray);

Any other suggestions?

Thanks!

I assume the array contains String objects. You can wrap each String object in another object that implements the Comparable interface, so you can ignore case:

class MyString implements Comparable
{
   public String s = null;

   public int compareTo( Object o )
   {
      return s.compareToIgnoreCase( ((MyString)o).s)
   }
}

When you sort the array of MyString objects, they will sort case-insensitive.

Most sort algoritums can take an optional comparator which is a class that has just the compareTo method (with 2 parameters). Which means that you don't need to wrap the strings to do the above -- cutting down on code. I'm not sure about the sort that takes an array, but most first class ordered containers will handle a comparator.
