for them?
6. Explain about interface methods and what modifiers are applicable
for them?
7. Can java class implement any number of interfaces?
8. If two interfaces contains a method with same signature but
different return types, then how we can implement both interfaces
simultaneously?
9. Difference b/w extends and implements keyword?
10. We cannot create an object of abstract class then what is
necessity of having constructor inside abstract class?
11. What is a marker interface? Give an example?
