Accessing and updating the values of a 2D array

In Java, accessing and updating values in a 2D array is done using the row and column indices. The general format is:

- **Accessing a value**: array[row][column]
- **Updating a value**: array[row][column] = newValue;

Popcorn Hack 1 (Part 2)

• Update the values of the array, you made in part 1 to the group members in another group

public class Main {
    public static void main(String[] args) {
       // the array from part 1
        String[][] pairs = {
            {"Sri", "Saathvik"},
            {"Aidan", "Tanav"}
        };

        // the update
        pairs[0] = new String[]{"Jonathan", "Tarun"};   
        pairs[1] = new String[]{"Ian", "Srijan"};  

        System.out.println("the updated pairs:");
        for (int i = 0; i < pairs.length; i++) {
            for (int j = 0; j < pairs[i].length; j++) {
                System.out.print(pairs[i][j] + " ");
            }
            System.out.println();
        }
    }
