Interfaces can also have default and static methods with a body.

Joins in SQL are used to combine data from two or more tables based on a related column.
Joins are used to retrieve data from multiple tables in a single query.
There are different types of joins such as inner join, left join, right join, and full outer join.
Inner join returns only the matching rows from both tables, left join returns all rows from the left table and matching rows from the right table, right join returns...
Autoboxing is the automatic conversion of primitive data types to their corresponding object wrapper classes.
Autoboxing allows primitive data types to be used as objects.
Auto-unboxing is the reverse process of autoboxing.
Autoboxing and auto-unboxing are performed automatically by the compiler.
Example: int i = 10; Integer j = i; // autoboxing
Example: Integer j = 10; int i = j; // auto-unboxing
