Q) Binding of parameters?



A)
->Supply values to the place holders (question marks (?)) is nothing but binding of parameters.
->these parameters are known as “in parameters”.
“in parameters” are those parameters whose values are not supply at query compilation time, instead, supplied at query execution time.
->Binding of parameters is done by calling Setxxx(int index,value) on PreparedStatement object. The first argument of the method is question mark number (starting number is 1) in the query. The 2nd argument id value.
->Setxxx() methods are mirror methods of the getxxx methods of ResultSet.

Ex:
ps1.SetInt(1,1001);
ps1.SetString(2,”prince”);
ps1.SetFloat(3,7000);
ps2.SetFloat(1,500);
ps2.SetInt(2,1001);

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...
