what is difference between public static and void in c#?

public − This is the access specifier that states that the method can be accesses publically. static − Here, the object is not required to access static members. void − This states that the method doesn't return any value.

Static variable are declared in the same place as instance variables, but with the keyword 'static' before the data type. While instance variables hold values that are associated with an individual object, static variables' values are associated with the class as a whole.

Static arrays are allocated memory at compile time and the memory is allocated on the stack. Whereas, the dynamic arrays are allocated memory at the runtime and the memory is allocated from heap.

The default access modifier in Apex is private, while in Java it is default. public in Java is not same as public in apex. public in Apex means the method or variable can be used by any Apex in this application or namespace. if you want to make something public like it is in Java, you need to use the global.

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Lets discuss the difference between static and dynamic binding in Java. Static binding happens at compile-time while dynamic binding happens at runtime. ... The binding of overloaded methods is static and the binding of overridden methods is dynamic.

Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value.

Static arrays, sometimes simply called arrays, are allocated with a fixed size while dynamic arrays increase their size when an insertion occurs and the array currently has no space for the new value. Dynamic arrays are not the same as dynamically allocated static arrays.

Static variables are common across all instances of a type. constant variables are specific to each individual instance of a type but their values are known and fixed at compile time and it cannot be changed at runtime. unlike constants, static variable values can be changed at runtime.

Difference is static variables are those variables: which allows a value to be retained from one call of the function to another. But in case of local variables the scope is till the block/ function lifetime. Local variables are non existent in the memory after the function termination.

public means you can access it anywhere while private means you can only access it inside its own class. Just to note all private, protected or public modifier are not applicable to local variables in Java.

Here are a few important differences between static and dynamic binding: Static binding in Java occurs during compile time while dynamic binding occurs during runtime. ... Overloaded methods are bonded using static binding while overridden methods are bonded using dynamic binding at runtime.

Static Constructor is called automatically before the first instance of the class or any static data is referenced. It is called only once for any number of classes instance is created. Private constructor is a special constructor that generally used in class that contains only static members.

Static binding happens at compile-time while dynamic binding happens at runtime. Binding of private, static and final methods always happen at compile time since these methods cannot be overridden. ... The binding of overloaded methods is static and the binding of overridden methods is dynamic.

Difference between void main and int main in C/C++ It also takes arguments, and returns some value. ... The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data.

A private variable is only accessible inside the class. A static variable belongs to the class rather than to an instance of a class. Notice that the variable DEPARTMENT is also final , which means that it cannot be modified once it is set.

Global vs Static Variables. Global variables are variables defined outside of any function. ... Static global variables are private to the source file where they are defined and do not conflict with other variables in other source files which would have the same name.
