int ()() d = {{1, 1}, {2, 2}};

int [][] d = {{1, 1}, {2, 2}};

int [][] d = {new int[2], new int[2]};

int (2,2) d = {new {1, 1}, new {2, 2}};

int [][] d = {{2}, {2}};

A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays."
