Task:
int[] ar = { {10,20,30}, {40,50,60}, {70,80,90}};

1) Print only first column values - 10,40,70

package Array;

public class Task5 {
public static void main(String[] args) {



    int[][] ar = {{10,20,30},{40,50,60},{70,80,90}}; 
    System.out.println(ar.length);

    for (int i = 0; i < ar.length; i++) {
        System.out.println(ar[i][0]);
    }


}
}

output:
3
10
40
70

2) Calculate sum of diagonal values - 10+50+90

package Array;

public class Task6 {
public static void main(String[] args) {
    int[][] ar = {{10,20,30},{40,50,60},{70,80,90}}; 

    int total=0;
    for (int i = 0; i < ar.length; i++) {
          System.out.println(ar[i][i]);
          total=total+(ar[i][i]); 
    }

    System.out.println(total);
}
}

output:
10
50
90
150

3) Sum of each row

package Array;

public class Task7 {
public static void main(String[] args) {
    int[][] ar = {{10,20,30},{40,50,60},{70,80,90}}; 

    int total=0;
    for(int row = 0; row

output:
10 20 30
60
40 50 60
210
70 80 90
450
