    • areNotInAscendingOrder

      public static <T extends Comparable<T>> boolean areNotInAscendingOrder(T... values)
      Checks if any of the values are not in an ascending order. The check is done based on the Comparable.compareTo(Object) method. E.g. if we have minPriority = 10, priority = 13 and maxPriority = 5 and Integer[] values = {minPriority, priority, maxPriority}. Then a call to areNotInAscendingOrder(Comparable[] values) will return true
      Type Parameters:
      T - the type of the comparable
      Parameters:
      values - to validate
      Returns:
      false if the not null values are in an ascending order or all the values are null, true otherwise

    • areNotInAscendingOrder

      public static <T extends Comparable<T>> boolean areNotInAscendingOrder(List<T> values)
      Checks if any of the values are not in an ascending order. The check is done based on the Comparable.compareTo(Object) method. E.g. if we have minPriority = 10, priority = 13 and maxPriority = 5 and List<Integer> values = {minPriority, priority, maxPriority}. Then a call to areNotInAscendingOrder(List values) will return true
      Type Parameters:
      T - the type of the comparable
      Parameters:
      values - to validate
      Returns:
      false if the not null values are in an ascending order or all the values are null, true otherwise

    • elementIsNotContainedInList

      public static <T> boolean elementIsNotContainedInList(T element, Collection<T> values)
      Checks if the element is not contained within the list of values. If the element, or the list are null then true is returned.
      Type Parameters:
      T - the type of the element
      Parameters:
      element - to check
      values - to check in
      Returns:
      true if the element and values are not null and the values does not contain the element, false otherwise

    • elementIsNotContainedInArray

      public static <T> boolean elementIsNotContainedInArray(T element, T... values)
      Checks if the element is contained within the list of values. If the element, or the list are null then true is returned.
      Type Parameters:
      T - the type of the element
      Parameters:
      element - to check
      values - to check in
      Returns:
      true if the element and values are not null and the values does not contain the element, false otherwise

    • elementIsContainedInList

      public static <T> boolean elementIsContainedInList(T element, Collection<T> values)
      Checks if the element is contained within the list of values.
      Type Parameters:
      T - the type of the element
      Parameters:
      element - to check
      values - to check in
      Returns:
      true if the element and values are not null and the values contain the element, false otherwise

    • elementIsContainedInArray

      public static <T> boolean elementIsContainedInArray(T element, T... values)
      Checks if the element is contained within the list of values.
      Type Parameters:
      T - the type of the element
      Parameters:
      element - to check
      values - to check in
      Returns:
      true if the element and values are not null and the values contain the element, false otherwise

    • min

      public static <T extends Comparable<T>> T min(T obj1, T obj2)
      Returns any element if obj1.compareTo(obj2) == 0

    • max

      public static <T extends Comparable<T>> T max(T obj1, T obj2)
      Returns any element if obj1.compareTo(obj2) == 0

    • elementsAreContainedInArray

      public static <T> boolean elementsAreContainedInArray(Collection<T> subset, T[] superset)
