Java doesn't support multiple inheritances for classes but it supports multi-level inheritance for classes and multiple inheritances in interfaces.

Let us we understand in detail why does java not support multiple inheritance?

class A

{          

           void show()

           {            } }

class B

{          

           void show()

           {            } }

class C extends A,B

{          

           public static void main(String args[])

           {

                       C obj=new C();

                       obj.show()

           }             }

In the above example compiler will never know which method to invoke. Because show() method is there in both classes and both classes have different implementation for show() method.

But in interface implementation is unique if interfaces have the same method…

i.e. interface I1

{

           show(); }

interface I2

{

           show(); }

class A implements I1,I2

{

           void show()

           {

                       .................

                       ..................            }            public static void main(String args[])

           {

                       A obj=new A();

                       obj.show()

           }

}

Here, only declaration of method given in interface but implementation given only in class. So, only method from implementing class is going to be executed.

SQL is a standard language for accessing and manipulating databases. SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987.

SQL is most important part of Database Management System.

Use of SQL:

SQL is responsible for querying and editing information stored in a certain database management system.

SQL offers great flexibility to users by supporting distributed databases, i.e. databases that can be run on several computer networks at a time.

SQL helps you to find the needed information or data easily.

SQL is a query language, not a programming language. You can easily write commands almost same as you write English.

It quickly stores and gets data from the database quickly. SQL is used for the query, insert, collect and manages data from the database.

 Almost every database system will need SQL for further processing.
