Q) java application on constructor overloading?





class book
{
       String title;
       String author;
       float price;
       book()
       {
              title="java complete reference";
              author="schidt";
              price=350;
       }//default constructor
       book(String t,String a,float p)
       {
              title=t;
              author=a;
              price=p;
       }//parameterized constructor
       void displaybookdetails()
       {
              System.out.println("title :"+title);
              System.out.println("author :"+author);
              System.out.println("price :"+price);           
       }
}//class book

class constructoroverloading {

       public static void main(String[] args) {
              book b1=new book();
              System.out.println("first book details");
              b1.displaybookdetails();
              book b2=new book();
              System.out.println("second book details");
              b2.displaybookdetails();
              book b3= new book("yhinking in java","euckle",750);
              System.out.println("third book details");
              b3.displaybookdetails();
       }//main
}//class

A)
Output :

first book details
title :java complete reference
author :schidt
price :350.0
second book details
title :java complete reference
author :schidt
price :350.0
third book details
title :yhinking in java
author :euckle
price :750.0

Q) What is JDBC driver? What is its role in java database connection?

A) ->A translation software written in java according o JDBC specification is nothing but “JDBC driver”. -> JDBC driver implements JDBC API. Use single API.

Ex: class A {        class B        {                      } //nested class, and inner class.because it is not static class. } //enclosing class or outer class. ->static class is declared in inside an another class then it does not become an inner class. Note: non-static nested class is known as “inner class”. In the above example class B is nested but not an inner class. Ex: class D {        static c        {                      } //nested class, but not an inner class , because of static class. } //outer class. ->we have three different kinds of inner classes. 1) Member inner class 2) Meth...
