Q) Develop a java application that creates 2 distances perform the addition of those distance and displays their sum?





A)

class distance{
       int feet;
       int inches;
       distance(int feet , int inches)
       {
              this.feet=feet;
              this.inches=inches;
       }
       void displaydistance()
       {
              System.out.println(feet+" feet"+inches+" inchess");
       }
       static distance add (distance one,distance two)
       {
              int f=one.feet+two.feet;
              int i=one.inches+two.inches;
              if(i>=12)
              {
                     f++;
                     i=i-12;
              }
              distance d=new distance(f,i);
              return d;
       }
}//distance type created

classexecutedistance {

       public static void main(String[] args) {
              distance d1=new distance(10,9);
              System.out.println("the first distance is :");
              d1.displaydistance();
              distance d2=new distance(9,10);
              System.out.println("the second distance is :");
              d2.displaydistance();
              distance sum=distance.add(d1,d2);
              System.out.println("the sum of their distance is :");
              sum.displaydistance();

       }

}

Output :

the first distance is :
10 feet9 inchess
the second distance is :
9 feet10 inchess
the sum of their distance is :
20 feet7 inchess

-> References are local to method
-> Objects are not local to method
-> d1, d2 are local to main ()

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. JDBC driver role: They are 4 roles   1)       Establishing connection between JDBC client and database server. 2)       Receiving JDBC method calls made by JDBC client while performing database (CRUD) operations. 3)       Translating java method calls into DBMS understandable calls and forwarding them to database server. 4)       Receiving the results from database server. Translating them into java format and handling over the same to the JDBC client.

Q) Explain about nested classes?

A) ->defining a class with in another class is known as nesting of the class. 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...
