I found this code in the Getting in Touch with your Inner Class
tutorial on this site, but I think you cannot create an inner class object as specified in the code
Inner i = Inner();
Shouldn't it be
Outer.Inner i = Inner();

class Outer
private int size ;
private String thoughts = "My outer thoughts";
class Inner
String innerThoughts = "My inner thoughts";
void doStuff()
// inner object has its own "this"
System.out.println( innerThoughts );
// and it also has a kind of "outer this"
// even for private data of outer class
class TestMe
public static void main( String args[] )
// instantiate me, the outer object
Outer o = new Outer();
// Inner i = new Inner();
// NO! Can't instantiate Inner by itself!
Inner i = Inner();
// now I have my special inner object
// OK to call methods on inner object

You're right - good catch. I'm moving this to the "Java Ranch" topic to be sure Paul sees it, as he's the one who could fix the error. (Hi Paul!) Thanks.
