How to use array?

Question

Where's column and row?

Answer 1

especially 2d is most common used.For Example:
int [][] arr = new int [2][3] ; // it looks like that:

// 1. column 2.column 3.column
arr[0][0] arr[0][1] arr[0][2] //1.row
arr[1][0] arr[1][1] arr[1][2] //2.row

// instead of int , u can string, long, float...,
