Ejemplo 1: por qué el método principal es público static void en java

public: “public” is an access specifier which can be used outside the class. 
When main method is declared
public it means it can be used outside class.static:To call a method we require object. Sometimes it may be 
required tocall a method without the help of object. Then we declare that 
method as static. JVM calls the main() method without creating
object by declaring keyword static.
If we make the main method non-static, 
JVM will have tocreate its object first and then call main() method which 
will lead tothe extra memory allocation.void:voidreturn type is used when a method does’nt return any value.main() method doesn’t return any value, so main() is declared as void.
