Now come to a multidimensional array.We can say that a 2d array is an array of array. GitHub Gist: instantly share code, notes, and snippets. A multidimensional array is mostly used to store a table-like structure.. Some have spatial relationships on a two-dimensional plane, a grid. To find number of columns in i-th row, we use mat[i].length. These arrays store … There are various ways using which you can print an array in Java as given below. 2. Solution We can solve this using recursion as well but need to take care of duplicates.We will sort the array, so all duplicates will be conitguous. For this two for loops are required, One to traverse the rows and another to traverse columns. Print 2D array in tabular format: To output all the elements of a Two-Dimensional array, use nested for loops. 1) Using while loop. 2D array. Creating an array in Java. Mkyong.com is providing Java and Spring tutorials and code snippets since 2008. You can use a while loop to print the array. first one for row and the second one for the column.
