What should be the output ?

using System;

class Program { 

    static void Main(string[] args) 

    { 

        Program ex = new Program(); 

        ex.setData(10, 20); 

        ex.getData(); 

        Console.Read(); 

    } 

    int i; 

    int j; 

    public void setData(int i, int j) 

    { 

        i = i; j = j; 

    } 

    public void getData() 

    { 

        Console.WriteLine("i=" + i + " , j=" + j); 

    } 

}
