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();

So you cannot begin execution of a class without its object if the main method was not static.OrMain is starting point of the program execution Main method is called by JVM there is no need for JVM tocreate an object of the class just to access Main function
In java how the class containing main is executed with out creating an object?
You may know that static methods in Java are executed even before the constructor of that class are called. Similarly, since the main method is static it gets executed first even before the others methods of the class are called. Since it is being called before the constructor, logically speaking you cannot have objects of that class.
