Q) What is autoboxing?




A)
->implicit conversion of a primitive type into object (wrapper) type is known as autoboxing.

Ex:


class autoboxing
{
       static void x(Integer i)
       {
              System.out.println(i);
       }
       public static void main(String[] args)
       {
              Integer i= new Integer(10);
              x(i);
              x(10);//autoboxing - it is done with jdk1.5 anf 1.6. but ir is not       in jdk 1.4
             
       }
}

Output:
10
10
->autoboxing and auto unboxing is not work in jdk1.4, these are work from jdk1.5 on works.

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...
