“Fill” is a static collection method, as one of several ways to instantiate a static list.<\/p>\n

If you want a list of several values, you could do something like this:<\/p>\n

\nval x = List(0, 0, 0, 0, 0)\n<\/pre>\n
But, fill makes this easier:<\/p>\n
\nscala> List.fill(0)(5)\nres22: List[Int] = List(0, 0, 0, 0, 0)\n<\/pre>\n
You can pass anything into this:<\/p>\n
\nscala> List.fill(5)(\"test\")\nres21: List[String] = List(test, test, test, test, test)\n<\/pre>\n
You can even make multi-dimensional arrays this way:<\/p>\n
\nscala> List.fill(2, 3)(0)\nres26: List[List[Int]] = List(List(0, 0, 0), List(0, 0, 0))\n\nscala> List.fill(2, 3, 4)(0)\nres27: List[List[List[Int]]] = \n  List(\n    List(\n      List(0, 0, 0, 0), \n      List(0, 0, 0, 0), \n      List(0, 0, 0, 0)), \n    List(List(0, 0, 0, 0),\n         List(0, 0, 0, 0), \n         List(0, 0, 0, 0)))\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
