srikanth I could not find any examples of a class created inside an interface. I used the code below to see how it would work. Prehaps someone else has more insight into this.
this code compiled and ran fine . So for your questions : 1)it is not possible in the java Laungage. false, I was able to implement the class in the interface.
2)The class is always public. not sure but I thank the answer is true 3)The class is always static. false 4)the class methods cannot call the methods declared in the interface. false
5)the class methods can call only the static methods declared in the interface false
another problem I had with the class in the interface is that the tryit method could not be declared abstract. I assumed the class it self would be abstract since it was in the interface but trying to set the methods in the class to abstract generated an error.
