Accessing multidimensional array using scanner, it works with a single array but not multi?.

Question

import java.util.Scanner;

public class Program {
public static void main(String[] args) {

int array[][] = {10, 5, 7, 2},{20,4,17,12};
System.out.println("Choose a value between 0-4");

Scanner scan = new Scanner(System.in);

int num = scan.nextInt();
int num2 = scan.nextInt();

int value = array[num][num2];

System.out.println(value + " < Your selected Value");
}
}

Answer 1

The problem isn't with accessing the array it's with initializing the array.

You use:
int array[][] = {10, 5, 7, 2},{20,4,17,12};
What should be:
int array[][] = {{10, 5, 7, 2},{20,4,17,12}};

Then it should work as expected.
