How to add a two-dimensional array directly to a hashmap?

Question

Instead of this:

int[][] someArr = { { 88, 35 }, { 11, 98 } };
mapDE = new HashMap<String, int[][]>();
mapDE.put("someKey", someArr);

I would like to do this in order to save a code of line:

mapDE = new HashMap<String, int[][]>();
mapDE.put("someKey", { { 88, 35 }, { 11, 98 } });

Any easy way to do this?

Answer 1

mapDE.put("someKey", { { 88, 35 }, { 11, 98 } }); does not compile because { { 88, 35 }, { 11, 98 } } wont ensure the type int[][]

You could try by this way:

    Map<String, int[][]> mapDE = new HashMap<String, int[][]>();
    mapDE.put("someKey",new int[][] { { 88, 35 }, { 11, 98 } });

Answer 2

Use this:

mapDE.put("somekey", new int[][]{
  { 0, 0 },
  { 0, 0 } });

Answer 3

You're very close, try the following:

mapDE.put("someKey", new int[][]{{88, 35}, {11, 98}});
