They are public because they must be accessible to the JVM to begin execution of the program. Main is the first method that would get executed in any class.
They are static because they must be available for execution without an object instance. you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static.
Or
Main is starting point of the program execution Main method is called by JVM there is no need for JVM to
create an object of the class just to access Main function

Why the main function is public and static?
The main function is public because it means it needs to be called by any object. I had to check this myself but if you try to make the main function in Java private it will give you a run time error. It is static because it is indicating it is a class method and it does not need to be instantiated. Without the static keyword you would need to do something like this Main main = new Main();
