// This Comparator uses a Collator to determine the
// proper, case-insensitive lexicographical ordering
// of two strings.
class IgnoreCaseComp implements Comparator {
  Collator col;
  IgnoreCaseComp() {
    // Get a Collator for this locale.
    col = Collator.getInstance(java.util.Locale.CHINA); //工厂方法
    // Have it consider only primary differences.
    col.setStrength(Collator.PRIMARY);
  }
  // Uses Collator's compare() method to compare strings.
  public int compare(String strA, String strB) {
    return col.compare(strA, strB);//采用Collator的compare方法
  }
