# Interview Questions

## Why is the main() method static in Java?

* Because the main() method needs to be called without creating an object of the class. Being static allows it to be directly invoked via the class name.

## Can the main() method be overloaded in Java?

* No, the main() method cannot be overloaded as Java runtime only calls the main() method that has the exact signature of:\
  `public static void main(String[] args)`

## Can the main() method be declared final in Java?

* Yes, declaring the main() method as final prevents it from being overridden in subclasses. This can be done to prevent tampering with the main method's logic.

## What is the significance of the String array parameter passed to the main() method?

* The String array (String\[] args) contains any command line arguments passed while invoking the class. We can access and use these arguments in the main() method.

## Can the main() method call itself recursively in Java?

* Yes, the main() method can call itself recursively similar to any other Java method. However, extreme care must be taken to ensure termination conditions are met to prevent infinite recursion.

## What if we declare the main() method as private in Java?

* Compilation error. The program will not compile if main() is declared private since it needs to be visible for the runtime to invoke it.

## Is it mandatory to have a main() method in a class for it to run in Java?

* No, if no main() method is present, the class can still be used by calling methods on an instance of that class from another class having main().

## What arguments get passed to the main() method in Java by default?

* By default, the main() method is called with no arguments. We have to explicitly pass command line arguments at runtime for them to be received in the main() method.
