Static Members Definition:

Static members are data members (variables) or methods that belong to the class itself rather than to its objects. Regardless of where and how they are used, static members always remain the same. Because static members are associated with the class, no instance of that class is required to invoke them.

In languages such as C# and Java, we can invoke static methods with the syntax clsName.Cls Name(args), where month name is the static method name and cls Name is the class name. Static variables can be accessed by using their class name: cls Name.Var Name, where Var Name is the name of the static variable.

In Java, a static member is a class member that isn’t connected with a class instance. Instead, every single is a class member. As a result, there is no need for a class instance to control the static member. The value of a static field remains constant across all instances of the class.

C++ data members that are static:

Static data members are members of a class that has the static keyword expressed. The properties of a static member are unique. These are the given below, have a look:

• No matter how many objects are produced, only one copy of that member is made for the entire class and shared by all.
• It’s set up before any of this class’s objects are produced, even before the main starts.
• It is only visible within the class, but it lasts the entire program.

There is only a single copy of a static variable in memory because it is connected to a class. All objects in that class share this copy.

The following are some of the characteristics of static members:

• All static members of the contained class, including private members, are accessible to a static member.
• Access control modifiers can be used to declare a static member.
• Without qualifying its name with the name of the contained class, a static member class can use any other static member.
• Any of the surrounding classes cannot have the same name as a static member class. Only top-level classes and other static member classes and interfaces can define static member classes and interfaces.
