Joins are used to retrieve data from multiple tables.
There are different types of joins such as inner join, left join, right join, and full outer join.

- Q5. Can static method be overriden/ overloaded?
- Ans.
No, static methods cannot be overridden but can be overloaded.
Static methods belong to the class and not to the instance of the class.
Overriding is not possible as it requires inheritance and static methods cannot be inherited.
Overloading is possible as it allows multiple methods with the same name but different parameters.
Example: public static void method() and public static void method(int a)
