      Modifier and Type Method Description
      static java.util.List<java.lang.Integer> asList​(int... values)  
      static <T> boolean equalsUnordered​(java.util.List<T> list1, java.util.List<T> list2)
      Compare two lists, same elements, order of the lists may be different, elements must have the same cardinality.
      static <T> T last​(java.util.List<T> list)  
      static <T> java.util.List<T> listDiff​(java.util.List<T> list1, java.util.List<T> list2)
      Asymmetric diff of two unordered lists, returning the elements in list1 not in list2.
      static <T> Pair<java.util.List<T>,​java.util.List<T>> listDiffBoth​(java.util.List<T> list1, java.util.List<T> list2)
      Diff of two unordered lists, returning the elements in list1 not in list2, and the elements of list2 not in list1.
      static <T> java.util.List<java.util.List<T>> permute​(java.util.List<T> c)
      Return a list of lists of all the elements of collection in every order Easy to run out of heap memory.
