The 2D array is based on a table structure which means rows and columns, and filling the 2d array cannot be done with simple adding to array operation. This tutorial demonstrates how to fill a 2d array in Java.
Thelengthfield is a property of the array object that returns the number of rows in the array. Here is an example of how to get the length of a 2D array in Java: int[][]array={{1,2,3},{4,5,6},{7,8,9}};intnumRows=array.length;intnumColumns=array[0].length;System.out.prin...
