At the time of developing jvm the development team by default make a only one method call i.e; 'main' method call in the jvm that's why when the call is loading into the jvm the jvm call the main method...and execution was starts..

Can you overwrite main function in java?
You can not overwrite a static method in Java,and 'main' is a static method.so,you can't overwrite the 'main'.
Why main method is static?
Main method in java is always static as main method id the only method from where the program execution starts,and as we all know that main method is defined inside a class so JVM needs to make a object of the class to call the method and objects are build inside the main method ,so to execute the main method it has to make objects of the class but objects are build inside main method so that's the reason that main method is static so that JVM can execute the main method without making its object as static members can be called by class anme only
What are the valid signatures of the main method of a class?
The main method can be declared as either of the below: public static void main(String[] args) or public static void main(String args[])
Why using the name main for main method in java?
If you run an java file(as an .class or .jar file) there's always 1 method being called: The main(String[] args) method.The method is only called once.Example of an main method:public static void main(String args[]) throws IOException {LoggingBootstrap.bootstrap();gui = new GUI();}In this case it only bootstraps the logger and uses the constuctor method of GUI(the graphical user interface of the program)
Is it compulsory to write static with void main?
Every C# application is started on the startup class' static Main method. Yes, it must be static, but void is not the only returned type. The 4 signatures:static void Main();static void Main(string[] arguments);static int Main();static int Main(string[] arguments);Ideally, there should be one and only one Main method in your application.
Why you use main method when you can use static method?
The main method is called by the jvm when your program is executed. The main method is a static method: public static void main(String[] args) {} A static method is method that can be run without instantiate the class (creating an object from it) The main method is a static method. No other static method could replace it's functionality. PS By static method do you mean static initialiser? I often use static initialisers instead of a main method, but in these cases you must still have a main method, albeit an empty one ie. public static void main(String[] args) {} Notice that the method has an empty body A main method must be used if you intend to accept parameters at run time from the jvm.
Can the main method call the other method if it is not defined as static?
No
Which method is called first of all other methods when any application executed in c sharp?
static method Main() of the start object/class.There are 4 different signatures of Main():static void Main();static int Man();static void Main(string[] args);static int Main(string[] args);The starting object/class can have only one of them. Other classes or objects may have Main() method as well. (But why would be the question, Main() is NOT a good OO method name anyway. Method name should be a verb or start with a verb)

How static member function main in java can be accessed by another function?
The main method can be called just like any other method. Just keep in mind that doing so can create infinite loops. Example: class MyClass { static boolean hasEnteredMain = false; public static void main(String[] args) { System.out.println("main()"); if(hasEnteredMain) { return; } hasEnteredMain = true; f(); } static void f() { System.out.println("f()"); main(null); } }
Why main is static?
The main method is static because the JVM would be invoking this method as the starting point of execution. If this is like other normal methods, the JVM would have to instantiate an object of the class before it can call it. This is not possible because this is the starting point. If the main method is static the JVM can directly call this by specifying the class name.
Can main method be overloaded illustrate with example program?
Yes, you can very well overload the main method but, the main method that would get invoked by the JVM when you try to run this class would be the main method that has the below signature: public static void main(String[] args) { ... } All other main methods would be accepted by the Compiler but only the above method would get called when you run the class
