In Java, multidimensional arrays are also applied as arrays of arrays. 2D(two-dimension i.e tabular form) array is the generally used and simplest multi-dimensional array(like excel sheet(grids)). 2D arrays are represented in a row-columns([3][4]) form, and the terms “rows”[3] and “columns”[4] are used in computing. Syntax…. Declaration – Syntax: Data_Type[][] Array_Name = new int[Row_Size][Cols_Size]; … Read more
