convert one dimensional array to two dimensional array java code example

Example 1: java two dimensional arrays

int[][] multiples = new int[4][2];     // 2D integer array with 4 rows 
                                          and 2 columns
String[][] cities = new String[3][3];  // 2D String array with 3 rows 
                                          and 3 columns

Example 2: how to convert one dimensional array into two dimensional array

x = x.reshape(-1, 1)

# remember to check shape of your variable using x.shape, if it shows
# (y, n) then it is already 2D, if it shows (y,) instead, it is 1D.
