Static keyword can be applied to
Class, field, method, properties, operator, event and constructors.
Static member belongs to the class and not to any object of the class.
They can be used without creating the instance of the class.
For e.g. Static Void Main()
It is called by the operating system on program execution
To access the static member we’ll use
ClassName.staticmember
When a variable is declared as static internally what happens is that all the instances of the class share the same static variable. A static variable is initialized when its class is loaded. If not
initialized explicitly then
it is initialized to zero for numeric variable
null in case of object references
false for boolean
StaticMethod– they can only contain static member and call other static method.
If we need to access them than it can be done through the object of that class
class Game
{
string getGameName()
{
……………….
}
public static void getNameThroughStatic(Game g)
{
g.getGameName(); // accessing static method
}
}
When to use them?
Well we can use them when we need to maintain information applicable to the entire class
suppose we have a class Employees there we can have a static count variable to keep track of no of employees.
class Employees
{
static in count=0;
public Employees()
{
count++;
}
~Employees
{
count–;
}
}
What are Static Constructor?
They can be used to initialize the static variables.
They are called automatically and before the instance constructor (if called any).
for above class
static Employees() // no other access modifiers for them
{}
What are static Classes?
A class whose objects can’t be created and which can only have static members. They can’t be inherited as well.
They can have static constructor
Why use static Classes?
It can be used to group related static method.

what is that you are saying
public static void getNameThroughStatic(Game g)
{
g.getGameName(); // accessing static method
}
static method can be accessed with Class name. it dont require an instance of class.

Code and definition posted above for static method is wrong. We can’t create object of static class and cant access static method by creating object of a class.
In above code, there is lot of mistake..
1st, Two return type cant be declared for a single method and 2nd we can’t access static method by creating object of a class. It should be accessed by class name like
Game.getGameName(); instead of g.getGameName();
Please check your code thoroughly before posting.
