Question

DESCRIPTION:

You will be given a 2-D string array, called matrix. The array has an unknown number of cells filled with data. Your goal is to iterate through the 2-D array and keep a count of how many cells contain the string "Angela".

INPUT:

All input has been handled for you:

• A filled 2-D string array.

PROCESSING:

• Determine the number of rows in the array matrix
• Determine the number of columns in the array matrix
• Use nested loops to iterate through the 2-D array.
• Keep track of the number of cells that contain the string "Angela".

OUTPUT:

• Print the result in the format below.
  

Sample input/output:

Input array  matrix	Output
Angela A B Angela C Angela D E Angela F Angela H	Rows: 4 Columns: 3 Angela: 5

Given code:

import java.util.Scanner;

public class Question2 {

public static void main(String[] args) {
Scanner in = new Scanner(System.in);
  
int count=0;
String[][] matrix = new String[in.nextInt()][];
in.nextLine();

while (in.hasNext()) {
matrix[count] = in.nextLine().split(" ");
count++;
}
