assigning a value to a class's field or property.
Static class
First, create a class that includes both static and non-static members.

variables are local static variables only when they are defined with the type modifier static.
Static variables can be applied wherever they can be applied, and once the application is successful, it will no longer accept the same application.
A static variable does not mean that it cannot change the value, and the am

Some member variables have a special data type, and they are initialized differently from the member variables of the normal data type. These special types of member variables include:A. ReferencesB. ConstantsC. StaticD.

A static member cannot be assigned in the class body because it is shared by all objects of that class. You assign a value to it in an object, and the member in the other object

The value of a static member is the same for all objects. Static members can be initialized, but can only be initialized outside of the class body.

If we want to share a single data within a range before we have a description of this chapter, we will set up global objects, but object-oriented programs are made up of objects, how can we share data within the scope of a class?
This issue is the focus of this chapter:
Class members or member functions declared as static can be shared within the scope of the
class myclass{Private arraylist _ coll = new arraylist ();
Myclass (){}
Myclass (INT size){_ Coll = new arraylist (size );}}
The above code will be compiled into the following code by the compiler
Public class myclass{Private arraylist _ Coll;
Myclass (){_ Coll = new arraylist ();}
Myclass (INT size){_ Coll = new arraylist ();_ Coll = new arraylist (size );}}
When you create a new myclass obje
