      static java.lang.Object growArrayToAtLeast​(java.lang.Object arr, int minLen)
      Method similar to growArrayBy50Pct(java.lang.Object), but it also ensures that the new size is at least as big as the specified minimum size.
      static java.lang.Object growArrayToAtMost​(java.lang.Object arr, int maxLen)
      Method similar to growArrayBy50Pct(java.lang.Object), but it also ensures that the new size is no bigger than specific maximum size.
