      • presizedList

        public static <T> java.util.List<T> presizedList​(int size)
        Returns a new list that is pre-sized to size, or Collections.emptyList() if empty. The list returned is never intended to grow beyond size, so adding to a list when the size is 0 is an error.

      • hasDuplicates

        public static boolean hasDuplicates​(java.util.List<?> list)
        Returns true if at least one pair of items in list are equals.

      • newLinkedHashMapWithExpectedSize

        public static <K,​V> java.util.LinkedHashMap<K,​V> newLinkedHashMapWithExpectedSize​(int expectedSize)
        Creates a LinkedHashMap instance, with a high enough "initial capacity" that it should hold expectedSize elements without growth.
