Which of the following ways to create an object of the Sample class given below will work correctly?

class Sample
{
    int i;
    Single j;
    double k;
    public Sample (int ii, Single jj, double kk)
    {
        i = ii;
        j = jj;
        k = kk;
    } 
}

byte b1 = 0xAB;
byte b2 = 0x99;
byte temp;
temp = (byte)~b2;
Console.Write(temp + " ");
temp = (byte)(b1 << b2);
Console.Write (temp + " ");
temp = (byte) (b2 >> 2);
Console.WriteLine(temp);

int val;
for (val = -5; val <= 5; val++)
{
    switch (val)
    {
        case 0:
            Console.Write ("India"); 
            break;
    }
    
    if (val > 0)
        Console.Write ("B"); 
    else if (val < 0)
        Console.Write ("X");
}
