{
       private int a;
       protected int b;
       void givedatatoA()
       {
              a=20;
              b=30;
       }
       void displayA()
       {
              System.out.println("a :"+a);
              System.out.println("b :"+b);
       }
}
class B extends A
{
       int c;
       void givedatatoB()
       {
              c=90;
              givedatatoA();
       }
       void displayB()
       {
              System.out.println("c :"+c);
       }
}

class simpleinheritance {
      
       public static void main(String[] args) {
              B b=new B();
              b.givedatatoB();
              b.displayA();
              b.displayB();
       }

}

Output :
a :20
b :30
c :90

Q) What is the purpose of JDBC?

A) -> Java application can do any task by making a method (function) call. ->java method calls are not understandable to database management system. They can understand only SQL statements. ->SQL statements can’t be directly used in a java application. Java compiler complains. ->therefore, we say that java environment and database environment are heterogeneous to each other. Purpose of JDBC: ->for any kind of java application to communicate with any kind of database (management system) in a standard manner, JDBC is used.
