Hi Friend,

Try the following code:

import java.util.*;

public class FindDiagonals{
public static void main(String args[])throws Exception{
Scanner input=new Scanner(System.in);
System.out.println("Enter the size of 2D array :");
int i=input.nextInt();
int d[][]=new int[i][i];
int j,k;
System.out.println("Enter the values of 2D array of "+i+" * "+i+" matrix ");
for(j=0;j<i;j++){
for(k=0;k<i;k++){
d[j][k]=input.nextInt();
}
}
for(j=0;j<i;j++){
for(k=0;k<i;k++)
System.out.print(d[j][k]+" ");
System.out.println();
}
System.out.print("Elements of Diagonal 1: ");
for(j=0;j<i;j++){
System.out.print(" "+d[j][j]);
}
System.out.println();
k=i-1;
System.out.print("Elements of Diagonal 2: ");
for(j=0;j<i;j++){
if(k>=0){
System.out.print(" "+d[j][k]);
k--;
}
}
}
}

Thanks
