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;

public class Main {
public static void main(String[] args) {
String[][] team = {
{"Eshaan", "Arthur"},
{"Miheer", "Saraas"},
{"Beijan", "Hanlun"}
};
// Display Array Code below
for(int i = 0; i < team.length; i++) {
for (int j = 0; j < team[i].length; j++) {
System.out.print(team[i][j] + " ");
}
System.out.println();
}
System.out.println("\nNew array:");
team[0][0] = "Antonio";
team[0][1] = "Brown";
team[1][0] = "John";
team[1][1] = "Billy";
team[2][0] = "Bobby";
team[2][1] = "Chris";
