The final keyword just means the value can’t be changed.
Without final , any object can change the value of the variable..
Is it possible for a static method to call a non static method?
A static method can call only other static methods; it cannot call a non-static method. A static method can be called directly from the class, without having to create an instance of the class. A static method can only access static variables; it cannot access instance variables.
Can we have 2 main methods in C#?
3 Answers. Yes – you can specify custom entry point if you have multiple Main methods. csc /main contains information on it: This option specifies the class that contains the entry point to the program, if more than one class contains a Main method.
What is a purpose of C# main method?
The Main method is the entry point of a C# application. (Libraries and services do not require a Main method as an entry point.) When the application is started, the Main method is the first method that is invoked. There can only be one entry point in a C# program.
What is the difference between public static and void in C#?

Why do we declare a method as static?

What happens when a method is static?
When a method is static, you can’t access non-static members; hence, your scope is narrower. … In some cases, your method only means something relative to an instance of your class, and it happens that its implementation doesn’t actually use any non-static field or instance.
Why we use static in main method?
