Inner classes

[Roopa Bagur]

Can someone explain whether the following code will compile or not.
public class Test009
{
public static void main(String args[])
{
Test009.Inner inner1=new Test009().new Inner(); //1
Inner inner2=new Test009().new Inner(); //2
inner2.method(); //3
}
class Inner
{
private void method()
{
System.out.println("0");
}
}
}

It compiles and gives output 0
Non-static inner class are pretty much dependent on the outer
class. They cannot exist without the instance of outerclass

If thats the case why is there a difference between statement 1 & 2 i.e the in the inner class variable type declaration.

Well, to create a reference of the type of the Inner class, you only need to specify the name of the Inner, 'if you are into the Outer class':
Inner inner;
But if you were outside the Outer class, you will need the long form:
Test009.Inner inner;
