Finding minimum and maximum in Java 2D array

Question

I have been trying to figure this out for a while and need some help. I need to find the min/max values and print them out for a multidimensional array. Here are the two way

Answer 1

package array;

public class Max_number {

// 2 5 7 9
// 3 6 8 1

public static void main (String []arg) {

    int a[][] = {{2,5,7,9},{3,6,8,1}};
    int max=a[0][0];
    for (int i=0; i<2; i++) //row
    {
        for (int j=0; j<4; j++) //coloum
        {
            if(a[i][j]>max)
            {
                max=a[i][j];
        }

    }

}
    System.out.println("maximum number is"+max);
}

}
