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

String[][] bob = new String[2][2];

bob[0][0] = "Ian";
bob[0][1] = "Srijan";
bob[1][0] = "Tarun";
bob[1][1] = "Jonathan";

bob[0][0] = "Aidan";
bob[0][1] = "Saathvik";
bob[1][0] = "Sri";
bob[1][1] = "Tanav";
