Q) What is wrong with the fallowing code?




interface I
{
       void m();
}
class B implements I
{
       void m()
       {
             
       }
}

A) It is wrong.

Method m() should be declared “public” , because every method in interface as default in public. If any child class method should not be weaker than super class, so that’s why an interface child class methods (which are overridden methods of interface) declared as public in the child class.

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...
