We can create a object of "static nested class ".
For eg. class Abc{
static class X{
void m()
System.out.println("static nested class method");
}
public static void main(String[] a)
{
X x=new X();
x.m();
}
}


but if you can not declare outer class as a static if u try to make outer class as static it will generate compile time error.
For eg static class X{}
It will generate compile time error as "Illegal modifier for the class".
