The following example shows how CollationKeys can be used to sort a list of Strings.

 // Create an array of CollationKeys for the Strings to be sorted. Collator myCollator = Collator.getInstance(); CollationKey[] keys = new CollationKey[3]; keys[0] = myCollator.getCollationKey("Tom"); keys[1] = myCollator.getCollationKey("Dick"); keys[2] = myCollator.getCollationKey("Harry"); sort( keys ); 
 //... 
 // Inside body of sort routine, compare keys this way if( keys[i].compareTo( keys[j] ) > 0 ) // swap keys[i] and keys[j] 
 //... 
 // Finally, when we've returned from sort. System.out.println( keys[0].getSourceString() ); System.out.println( keys[1].getSourceString() ); System.out.println( keys[2].getSourceString() );
