Anonymous inner classes must implement interfaces or extend other classes.
Step by step
Solved in 2 steps
- Anonymous inner classes must implement interfaces or extend other classes in order to be considered complete.True or False: An anonymous inner class must implement an interface or extend another class.Because a class may inherit from several interfaces, interfaces help establish stronger is-a connections. whether anything is real or fake
- Interfaces are used to define stronger is-a relationships because one class can inherit multiple interfaces. Ture or false(Abstract Classes vs. Interfaces) Compare and contrast abstract classes and interfaces. Why would you use an abstract class? Why would you use an interface?Describe one advantage of requiring a class to implement an interface.
- True or False ___(7) An object can be created from an interface. ___(8) An object in a super class can be assigned to a subclass variable. ___(9) Overriding and overloading a method is the same.Abstract classes and interfaces may be used interchangeably to specify the behavior of objects.How do you know whether you need an interface or an abstract class?How are interfaces different from abstract classes?
- Question 15 A class can inherit from just one base class, but it can implement multiple interfaces True FalseInterfaces provide more advantages than abstract classes.Computer Science we have learned about interfaces knowledge. Interfaces are preferred to define a common supertype for unrelated classes. Interfaces are more flexible than classes. You may design and consider the Animal class , and then you may suppose the how To Eat method is defined in the Animal class.
