I am giving an example code here. Try to analyze further.
<pre>
interface Inter {
class InnerClass {
}
static class NestedTopLevelInnerClass {
}
interface InnerInter {
}
static interface NestedInter {
}
}
class Test {
void m1() {
Inter.NestedTopLevelInnerClass c1 = new Inter.NestedTopLevelInnerClass();
}
}
</pre>

I understand why a,b,c are right. But can anyone explain why d is wrong? static method can't have static class inside it?
Thanx

I think I got the answer. Static block can't be included in a method.

I'm not sure a is right. Although it will compile it is not a "member" class. Inner Classes of an interface are inherently static ( top-level ).
