Why main method is static and public?

Java program’s main method has to be declared static because keyword static allows main to be called without creating an object of the class in which the main method is defined. In this case, main must be declared as public , since it must be called by code outside of its class when the program is started.

    public static is a static method that is accessible to external callers. Memory usage is identical in both cases: any variables declared in the method are scoped to the method-call itself (as an implementation detail: via the stack; also: I’m assuming no “captured variables”, and no async or yield usage),

    What is a public void?

    public void = a non-static method which allows public access and again returns nothing. This means it is available to anyone just as above, but this time because it is not static it is associated with an instance not the class itself.

    What is static void?
