hi,
static is a reserved keyword in java. a keyword static lets a method run without any instance of the class. Static means behaviour is independent of any instance variable. Math class is example of static.

points to remember regarding static

1) static methods can'ts use non-static methods, either.
2) value is the same for all instances of the class.
3) static final variables are constants.
4) static variables get default values just like instance variables.
5) static variables are shared.
6) all instances of the same class share a single copy of the static variables.
7) all the static variables is initialized only one time when class is loaded not every time when new instance is made.

static classes are usually a namespace resolution than about an implicit relationship between the outer class and inner class. Actually static class
is just like a static member of a class. and behave just like a static method.
If static keyword is used in amethod or a variable then it means that it is not instance specific. As it is, static nested class does not have access to the instance of the outer class. As the regular inner class enjoys the special
relationship with a outer class ,a static nested class does not. It is simply a noninner class scoped within another.
