Q) Modify the above application to implement Exception handling




A)
Note:
->Identify doubtful code in the application that may cause exception, placing it in try block and writing corresponding catch block(s) is nothing but Exception handling.

//withhandling.java

class withhandling {

       public static void main(String[] args) {
              int n,d,q=1;
              System.out.println("program is started :");
              n=Integer.parseInt(args[0]);
              d=Integer.parseInt(args[1]);
              try
              {q=n/d;
              System.out.println("the result of division is :"+q);
              }
              catch(ArithmeticException e)
              {
                     System.out.println("division failed second input value shouldn't be zero");
              }
              System.out.println("the application completely executed");
             
       }

}

Run :
java withhandling 10 0

->whenever enter 10 0 , then the arithmetic exception is raised by JVM and creates that object and throws that. That object is catched by catch block.

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...
