      public static List<Integer> intArrayToList​(int[] ints)
    • parseInt

      public static int parseInt​(String valueFor)
    • sneakyThrow

      public static <T extends Throwable> RuntimeException sneakyThrow​(Throwable t) throws T extends Throwable
      Re-throw t (even if it's a checked exception) without requiring a throws declaration.

      This function declares a return type of RuntimeException but will never actually return a value. This allows you to use it with a throw statement to convince the compiler that the current branch will not complete.

      
       throw Util.sneakyThrow(new IOException());
