Confused over initialisation of instance variables

I'm studying up for the SCJP exam, upon doing some mock tests I came across this one :

It asks what is the output of the following :

class TestClass
{
   int i = getInt();
   int k = 20;
   public int getInt() {  return k+1;  }
   public static void main(String[] args)
   {
      TestClass t = new TestClass();
      System.out.println(t.i+"  "+t.k);
   }
}

I thought it would be 21 20, since t.i would invoke getInt, which then increments k to make 21.

However, the answer is 1 20. I don't understand why it would be 1, can anyone shed some light on this?
