class outer
{
protected class inner
{
public inner()
{ System.out.println("in inner");
}
}
private inner p1;
outer()
{System.out.println("in constructor of outer class");
p1=new inner();//1
}
public static void main(String a[])
{ new outer(); }
}
AT line 1 i.e even before an object of outer class is created
inner class object is created.How is it working??? since
innerclass can be created after outer class object is created.
Thanks!

Actually, the outer object has been constructed at line 1. The compiler supplies a call to the Object constructor as an unseen first line, so by line 1 the memory for the object has been reserved and initialized to 0.
