Dynamic Way: Using InputStreamReader
This is another technique to insert the values by accepting the values from the user.
Program 19 Write a Java program to accept numbers into a 3 × 3 array and then calculate the sum of even
numbers present in odd positions.

2 class SumEvenInOddPositions
3 {
4 public static void main(String args[]) throws IOException
5 {

InputStreamReader isr = new InputStreamReader(System.in);
7 BufferedReader br= new BufferedReader(isr);
8 int n[ ][ ] = new int[3][3];
9 int i, j, s=0;
10 for(i = 0;i<3; i++)
11 {
12 for(j= 0; j<3; j++)
13 {
14 System.out.print ("Enter a number: ");
15 n[i][j] = Integer.parseInt ( br.readLine() );
16 }
17 }

19 for( i = 0; i<3; i++)
20 {
21 for(j=0; j<3; j++)
22 { if(n[i][j]%2 == 0 && i%2!= 0 && j%2!=0)
23 s = s + n[i][j];
24 }
25 }
26 System.out.println ("Sum of Numbers: " + s);
27 }
