Following example helps to determine the rows and columns of a two-dimensional array with the use of arrayname.length.
Following example helps to determine the upper bound of a two dimensional array with the use of arrayname.length.
public class Main { public static void main(String args[]) { String[][] data = new String[2][5]; System.out.println("Dimension 1: " + data.length); System.out.println("Dimension 2: " + data[0].length); } }
The above code sample will produce the following result.
Dimension 1: 2 Dimension 2: 5
