Locale-sensitive sorting refers to the process of sorting strings or other data types based on the rules and conventions of a specific locale. A locale is a set of parameters that defines the user’s language, region, and any special variant preferences that the user wants to see in their user interface. Different locales have different rules for how strings are sorted and compared.
For example, in English, the sorting order is generally straightforward and follows the ASCII values of characters. However, in languages like German, characters like “ä”, “ö”, and “ü” have special sorting rules. Similarly, in some Asian languages, the sorting order can be quite complex.
Java provides the
Collator class in the
java.text package for locale-sensitive sorting. You can create an instance of
Collator for a specific locale and then use it to compare strings in a way that is appropriate for that locale. Similar
Collator class is now available in Salesforce with Winter’24 release.
This short < 6 mins video gives a demo of the Collator class and explains how, and when it should be used, along with tips on where it shouldn’t be used.
You can run this code snippet in your Winter’24 Sandbox or pre-release org, needs API version 59.0 and beyond.
