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 to call 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.
void : void return type is used when a method doesn’t return any value . main() method doesn’t return any value, so main() is declared as void.
Signature : public static void main(String[] args) {}
