/*1. Fill a 10x10 matrix 2. Output to console as shown below Implement through two separate methods | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| | [phone]| */

Below is a Java example with two methods: one fills a 10x10 matrix with the text "[phone]" in each cell, and the other prints it to the console in a format where each row of the matrix is displayed as a line with vertical bars and spaces, as in the example.

public class PhoneMatrix {

    private static final int SIZE = 10;
    private String[][] matrix = new String[SIZE][SIZE];

    // Method to fill the matrix
    public void fillMatrix() {
        for (int i = 0; i < SIZE; i++) {
            for (int j = 0; j < SIZE; j++) {
                matrix[i][j] = "[phone]";
            }
        }
    }

    // Method to print the matrix
    public void printMatrix() {
        for (int i = 0; i < SIZE; i++) {
            StringBuilder sb = new StringBuilder();
            sb.append("|");
            for (int j = 0; j < SIZE; j++) {
                sb.append(" ").append(matrix[i][j]);
            }
            sb.append("|");
            System.out.println(sb.toString());
        }
    }

    public static void main(String[] args) {
        PhoneMatrix pm = new PhoneMatrix();
        pm.fillMatrix();
        pm.printMatrix();
    }
}

The output will look like:

| [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone]|
| [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone] [phone]|
... (total 10 lines)

If you need to output only one element per line, as in the example, you can modify the printMatrix method to print one element per line.
