Clarification of Inner classes

[Swati Jambhale]

Hello everybody
This is some discussion about Inner Class

There a 4 categories of "nested" classes
1)Top-level Nested classes and Interfaces
2)Non-Static Inner classes
3)Local classes
4)Anonymous classes
2,3,4 collectively known as "inner" classes
and Top-level Nested classes and Interfaces(1) are called static inner classes(I think so).
Am I right?
So if the question is that inner classes can be declared static so what we have to select either yes or no ? as inner classes(2,3,4 categories ) we cannot use a static keyword(they can be implicitly static if they are defined in static context(i.e static method,static initializer)
Please clear doubt and anwer this.I am little bit confused.
Thanx
Swati

the answer is true.
the division is into top-level nested class and nested inner class only, the former being the static one.
the term inner class is used for all classes declared inside another class.

see this code compile and run fine.
note that i have used "static" key word with the class inner.
--------------------------------------
class outer{
static class inner{
}
}
public class outer1{
public static void main(String args[]){
}
}

All the 4 types are called at Inner class. For top-level nested class (static inner class) rules are completely differnt that other 3. But still it is called as Inner class
