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
Code Example: package delftstack; import java.util.Scanner; public class Fill_Array { public static void main(String[] args) { System.out.print("Number of rows for 2d array: "); Scanner input = new Scanner(System.in); int Row = input.nextInt(); System.out.print("Number of columns ...
