Java static methods have many restrictions over themselves: They can only call static methods within from them. Java static methods can only access static data members or fields. Java static methods cannot refer this and superAs Java static fields are called class variables, likewise, static ...
It’s necessary to keep in mind that the static methods can only access the class’s static methods and static data members. Since they pertain to particular instances of the class, they are unable to access the non-static data members or methods. Demonstration of Accessing the Static Function...
Note that static methods can only access static class members. You can have static methods inside a static class or a non-static class. Also, you can have a static constructor in a static class or a non-static class. A static constructor is used to initialize the static members of a...
The keywordthisdenotes an implicitly declaredpointerto itself — to a specific instance of the class, in the context of which the method is executed. It can be used only in non-static methods of the class. Pointer this is an implicit non-static member of any class. In static functions you...
Static MembersA non-static class can contain static methods, fields, properties, or events. The static member is callable on a class even when no instance of the class has been created. The static member is always accessed by the class name, not the instance name. Only one copy of a ...
Static Methods Static methods are the same as static properties, a static method can access only static properties of the class and access to the non-static properties is illegal and lead to a compilation error. Static methods cannot be virtual Note: Static class properties and methods can be ...

When modifying a member function in a class declaration, the static keyword specifies that the function accesses only static members.Static data members of classes must be initialized at file scope.In recursive code, a static object or variable is guaranteed to have the same state in different ...
