HOW TO DIAGONAL SUM OF 3*3 MATRIX IN JAVA?


INPUT:-


import java.util.Scanner;

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

Scanner sc = new Scanner(System.in);
int n[][]= new int[3][3];
int i,j,sum=0;

System.out.println("Enter your element : ");
for(i=0;i<3;i++){
 for(j=0;j<3;j++){
 n[i][j]=sc.nextInt();
}
}

System.out.println("Your elements : ");
for(i=0;i<3;i++){
 for(j=0;j<3;j++){
  System.out.print(" " + n[i][j]);
}
 
 System.out.println();
}

System.out.println("Your sum Elements ");
for(i=0;i<3;i++){
 for(j=0;j<3;j++){
  if(n[i]==n[j]){
    sum=sum+n[i][j];

System.out.println(" " + n[i][j]);
  
 }
}
}

System.out.println("=" + sum);
}
}
