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

∙ 13y agoThe keyword static simply means that the method does not need to be assigned to an instance of an object. Because the main method is the first method executed, it is not attached to an instance.

∙ 11y agoStatic is a keyword.Static declares main() as one that belongs to the entire class and not a part of any objects of the class.It allows main() to be called without having to instantiate a particular instance of a class.Its neccessary that main() is called by java interpreter before any object is maid..Without creating object,OS called the main() thats why it used Static keyword...

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'.
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[])
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.
How do you invoke static methods?
if some method is static, then you can not call that method through the oobject of that class. but the name of the class. let us see a example: class Test { int a; int b; static void show() { System.out.println("we are in show"); } } class Main { public static void main(String args[]) { Test t=new Test(); t.show();\\thiss is an erroraneous code. because, the method "show()" is static. Test.show();\\this is correct } Arnas Sinha
Does the order of public and static declaration matter in main method?
No
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 you overwrite main function in java?

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)

Why is it the main method is a static method?
It doesn't need to be shared among several objects.
Does the order of public and static declaration matter in main method?
No
Why static is used in main method?
It is declared static because the JVM would need to execute the main method and if it is not static the JVM would need an object of the class to access the method. How can the JVM get an object of a class without invoking it. since it is static, the JVM can easily access it without this need to have an object of the class.
Is there any change by interchanging the position of main in Public static void main in java?
No. You can write it in as many ways as you want. The words public, static and void can be interchanged during the method declaration and still the main() method will continue to work in the same way. i.e., public static void main(String[] args) is the same as static public void main(String[] args) However, if you miss either of these 3 keywords from the method signature, the compiler will still let you compile the method, but it just won't be the main method that can be used to start the program execution.
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.
