Q) What is wrong with the fallowing code? How to fix it?




A)
class throwsexample
{
       void x() throws InterruptedException
       {
              Thread.sleep(1000);
       }
       void y()
       {
              x();
       }
       void z()
       {
              y();
       }
}

->the above code cause compilation error at x() class in y() method.
->Reason is x method has “checkedException” in it specification.
->we can fix the in two ways.

Case 1:
void y() throws InterruptedException
{
       x();
}

Case 2:
void y()
{
       try
       {
              x();
       }
       catch(Exception e) //or catch(InterruptedException e)
       {      }
}

Note :
If we use case 1 solution, the above code causes another compilation error. Because z() is calling y() method.

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...
