    • qsort

      public static void qsort(Vector strings)
      Sort a vector of strings using the Qsort algorithm. The compareTo method of the String class is used for comparison.
    • qsort

      public static void qsort(Object array) throws IllegalArgumentException
      Sorts an array of the basic types (ints, floats, bytes, etc.) or Strings. The sort is in increasing order, and is case-sensitive for strings. Sorting an array of booleans or an array of objects other than Strings is not supported.
      Parameters:
      array - The array to sort in place.
      Throws:
      IllegalArgumentException - if array is not an array of the types listed above.
    • qsort

      public static void qsort(Object array, Sort.Compare compare) throws IllegalArgumentException
      Sorts an array. The specified comparator is used to control the sorting order. Arrays of any type may be sorted, depending upon what the comparator accepts.
      Parameters:
      array - The array to sort in place.
      compare - The comparator for sort order.
      Throws:
      IllegalArgumentException - if array is not an array.
